Have tested this against two different Nvidia graphics cards on ununtu (running the non-free Nvidia drivers) and Nvidia drivers seem to be completely immune to the crash. The crash did occur on a different machine also running "intel" driver and using "Mobile Intel® GM45 Express Chipset" so this is looking like something that depends on the particular graphics driver in use.

[Bug 103933] Re: Java install via Add/Remove crashed
I have seen the same error with the missing libjli.so when installing Java into an ubuntu chroot. Making sure that the /proc was correctly mounted in the chroot caused the error to go away. Seems that the binary /usr/lib/jvm/java-6-sun-1.6.0.00/bin/java checks inside its own /proc/self/exe to find a path, and then mangles that path to find the shared library files. In other words, the libraries are found in a path RELATIVE to the running executable rather than normal absolute library paths. This allows it access to libraries outside the standard ldconfig system. I would guess that such a method might be fragile so hopefully this gives people a hint about where to look for problems. -- Java install via Add/Remove crashed https://bugs.launchpad.net/bugs/103933 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 242844] Re: [ooo-build] cannot start OpenOffice.org with xvfb-run
On close inspection the soffice script is not the real culprit because although it always backgrounds the binary it also has "wait $!" right afterward so the critical behaviour occurs at a deeper level when the binary forks various layers of itself. I'd like to just add a comment here that it should not be a guessing game to figure out whether a program will detach itself or not. Consider this file: /usr/lib/mime/packages/openoffice.org-writer The contents get into /etc/mailcap when /usr/sbin/update-mime runs, and hence various programs (for example the "mutt" email client) are instructed how they should execute OpenOffice in order to display a file. The current setting is: soffice -no-oosplash -writer '%s' Sadly, this will detach if OpenOffice is running somewhere on the desktop, but it will not detach should this be the first instance of OpenOffice. In other words, arbitrarily it may or may not detach for reasons unrelated to (and unknowable to) the program that tries to invoke the MIME entry. By the way, the "-no-oosplash" option still shows a splash screen (go figure), the open office wiki does not document the "-no-oosplash" option either (maybe it is not a supported option). What should happen is that certain command line options force it to NEVER detach, strictly if those options are present. In every other situation it should ALWAYS detach because OpenOffice is primarily an interactive desktop application. The behaviour of a command should never depend on factors beyond the options of that command, otherwise everyone is back into guessing games. For what it's worth, the /usr/bin/oowriter script does appear to always detach as far as I can check. Would be nice if the OpenOffice website would make more of an effort to document the supported command line options so people working with this had some idea of what is supposed to happen. -- [ooo-build] cannot start OpenOffice.org with xvfb-run https://bugs.launchpad.net/bugs/242844 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 408016] Re: Xorg crashes when handed bad xrender glyph data
Out on a limb, but the info might help someone :-( I've been tinkering with CentOS v5.4 and compiling wine-1.1.29-fe.tar.bz2 to run my EXE program. I've run up against similar problems (same hardware as above). Versions are: xorg-x11-drv-i810-1.6.5-9.25.el5 xorg-x11-server-Xorg-1.1.1-48.67.el5 Just for reference the RedHat package for i810 contains both of the drivers: /usr/lib/xorg/modules/drivers/i810_drv.so /usr/lib/xorg/modules/drivers/intel_drv.so and I'm using the "intel" driver, although the i810 driver also works on the same hardware. X does NOT crash for me in this configuration, but neither will wine actually run, I merely get the error message: X Error of failed request: BadLength (poly request too large or internal Xlib length error) Major opcode of failed request: 155 (RENDER) Minor opcode of failed request: 20 (RenderAddGlyphs) Serial number of failed request: 76507 Current serial number in output stream: 76512 If you check upstream ... http://cgit.freedesktop.org/xorg/xserver/tree/render/render.c ... you can see there is no NULL pointer check on pDstPix around line 1160 so I can't explain why the RedHat version does not crash in the same place, don't have time to go through it with a fine tooth comb.

[Bug 408016] Re: Xorg crashes when handed bad xrender glyph data
Made a tiny bit more progress, trying to get upstream wine bug re-opened but they want to fob the blame onto X11 and ignore their own problems, so chance of a quick solution is unlikely. Summary of the wine problem as far as I can tell: badly behaved win32 exe programs will call CreateFontIndirect() with bogus parameters and somehow under real Microsoft Win-XP these programs actually work. Under wine the bogus parameters gumby up the font metric calculator, which in turn cranks the handle on the X11 drivers -- whole lot of code, not many error checks. Getting X11 fixed might be a good step towards getting other buggy applications fixed, then they can stop trying to blame everything on the X server! I'll be patching up my own version of wine but I hesitate to post any public patch because it is rather a delicate matter to deal with badly behaved exe programs in a way that maintains maximum Microsoft compatibility. Doing the job right requires excellent understanding of how the win32 fonts work and a bit of research into how Microsoft deal with the questionable cases. I've gone about as far as I can go with this so I would appreciate someone pushing my NULL pointer check into the X server code and close off this bug.

Public bug reported: If you run with -x4 or similar to output a CSV and then load up the CSV into a spreadsheet (e.g. gnumeric) then you see the columns don't line up with the headers properly. I believe that two extra header items are required. This is with Ubuntu 10.04.2 LTS bonnie++ version 1.96 Note that I recompiled from source to give bigger values to Seeks and UpdateSeek in order to test a RAID system that is faster than the standard bonnie++ compile values can cater for.

[Bug 924100] Re: CSV headers are wrong -- two missing columns
Here is the same in gnumeric format. Note that the columns do not line up. It does not make sense that the file_size would be 1 and the io_chunk_size would be 1327979580 because actually these headers should be two steps over. Actually file_size should really be 33000M and io_chunk_size should be 4k. Most probably the two missing columns in the header are "concurrency" and "random_seed", that's my best guess. This would just require a change to a print statement to fix (but it makes a big difference when reading out the results). ** Attachment added: "2012-01-31_bonnie.gnumeric" https://bugs.launchpad.net/ubuntu/+source/bonnie++/+bug/924100/+attachment/2702273/+files/2012-01-31_bonnie.gnumeric -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/924100 Title: CSV headers are wrong -- two missing columns To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bonnie++/+bug/924100/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 919429] [NEW] Munin "IO Service Time" graph gives completely implausible numbers
Public bug reported: Recently a process wrote lots of data to the disk (and I'll take responsibility for that) but the "Disk IOs per device" went up (makes sense) and the "Disk latency per device" also went up (yup, so far so good) but the "IO Service time" strangely went down! Yes, it showed more latency but less service time. That's incredible. I'm incredulous. I've been suspicious of this for some time, because I absolutely know that /dev/sdc is a faster device than /dev/sda and /dev/sdb and for a long time it has been showing the lowest latency and the highest service time. It always did seem weird, but now I'm sure these numbers are bogus. ** Affects: munin (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/919429 Title: Munin "IO Service Time" graph gives completely implausible numbers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/munin/+bug/919429/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 919429] Re: Munin "IO Service Time" graph gives completely implausible numbers
Here is the offending graph, from munin. NOTE: the purple line is the fast drive, and the yellow line is a slower drive, but for some strange reason the yellow line goes DOWN under additional load (should go UP I would expect). Also, the results are completely the other way to the latency graph. ** Attachment added: "IO Service time - by week" https://bugs.launchpad.net/ubuntu/+source/munin/+bug/919429/+attachment/2684645/+files/iostat_ios-week.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/919429 Title: Munin "IO Service Time" graph gives completely implausible numbers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/munin/+bug/919429/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 919429] Re: Munin "IO Service Time" graph gives completely implausible numbers
Here is the graph of the latency, also from munin. Showing the exact opposite to the other graph. This one gives an answer that I believe is correct (or at least it is plausible). Note that /dev/sdc is the fastest drive, and shows the lowest latency. Also note that when loaded heavily, the latency on /dev/sda and /dev/sdb go up (they are RAID mirror so they move together). ** Attachment added: "Disk latency per device - by week" https://bugs.launchpad.net/ubuntu/+source/munin/+bug/919429/+attachment/2684669/+files/diskstats_latency-week.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/919429 Title: Munin "IO Service Time" graph gives completely implausible numbers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/munin/+bug/919429/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 919429] Re: Munin "IO Service Time" graph gives completely implausible numbers
Just for reference, here is a graph of IO operations, showing the additional load. The green line is /dev/md0 but that is a RAID mirror of /dev/sda and /dev/sdb so they are taking the load. NOTE: the load on /dev/sdc is constant and would typically be the drive taking the most load.

[Bug 919429] Re: Munin "IO Service Time" graph gives completely implausible numbers
I can see one problem in the file /usr/share/munin/plugins/iostat_ios as
follows:
LINE 202: print("${dev}_rtime.value ", ($rtime_diff != 0) ?
($rio_diff / $rtime_diff) : 0, "\n",
LINE 203: "${dev}_wtime.value ", ($wtime_diff != 0) ?
($wio_diff / $wtime_diff) : 0, "\n",
LINE 204: );
Here we see it divides number of IO operations by time in milliseconds. However
the graph has the vertical axis in seconds. Dividing by time gives Hz never
back to seconds again. So the graph results are really in Hz (not a useful unit
given the context we are working with here). I suggest that the calculation
should be:
LINE 202: print("${dev}_rtime.value ", ($rio_diff != 0) ?
($rtime_diff / $rio_diff) : 0, "\n",
LINE 203: "${dev}_wtime.value ", ($wio_diff != 0) ?
($wtime_diff / $wio_diff) : 0, "\n",
LINE 204: );
There's another (minor) problem which is to say that returning 0 in a situation
where no IO has occurred is a lie, should return NaN or NA but if you read the
Munin protocol specification (see link below) it claims "Output must be integer
or decimal number," so the have no provision for a plugin saying "hey, this
value does not exist right now" and that's strange because the RRD system does
support NaN for missing values -- but that's a bigger problem for another day.

[Bug 919429] Re: Munin "IO Service Time" graph gives completely implausible numbers
Agree that the IO Service time is made somewhat redundant by the Disk Latency graph which shows much the same information. However, IO Service time itemises read and write, and after coming this far, seems a shame not to make the small fix to get it working properly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/919429 Title: Munin "IO Service Time" graph gives completely implausible numbers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/munin/+bug/919429/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 919429] Re: Munin "IO Service Time" graph gives completely implausible numbers
Here is my suggestion, taking into account the "U" to mean NaN and also
I note that you can get deep negative spikes when the counters clock
over (unless I'm mistaken they are 32 bit counters, even on a 64 bit
kernel, and yes I do seem to have managed to clock at least one over).
LINE 202: print("${dev}_rtime.value ", ($rio_diff > 0 and $rtime_diff > 0) ?
($rtime_diff / $rio_diff) : 'U', "\n",
LINE 203: "${dev}_wtime.value ", ($wio_diff > 0 and $wtime_diff >
0) ? ($wtime_diff / $wio_diff) : 'U', "\n",
LINE 204: );
I've tested this for about half a day and it looks much nicer than the old
version, less clutter. When IO is not happening on a drive, the trace goes
away, and I think that's what should happen (people might for example use a
drive only for backups or some other intermittent activity).
