Howdy...
I've got a few different problems/symptoms, I suspect they are related.
# The System
RH 6.2 (*KRUD Distro) - AMD K6 450mhz - 64mb RAM - kernel-2.2.15 w/
2.2.25-ow1 patch. - 13 gig IDE drive - ATI AGP graphic card w/ 8 mb
VRAM - 330mb swap disk.
The system was installed clean on freshly formatted disk. It's a stand
alone machine, using dialup PPP. Almost all daemons are turned off
(HTTP, etc). The problems were occuring when I was using
kernel-2.2.14. I upgraded the kernel trying to solve the problem.
Problems occur in root level login shell (run level 3), running X
windows under various window managers (AfterStep 0.18.1, Sawfish 0.24
and Enlightenment 0.16.4 ).
(*KRUD = Kevens Redhat Uber Distribution # 6.2 - 20000430)
# Problem 1 -- VM: killing processes
>From a *cold boot* I immediately log into the root shell. I run "top"
and it shows me:
mem: 63168K av, 12684K used, 50484K free, 8140K shrd, 1716K buff
Swap: 337324K av, 0 K used 337324K free, 6164K cached
>From the login shell I try to "cp -Rf" a large directory to a different
partition. It chugs away for a while and then reports
VM: is killing processes cp
And then it completely locks up the machine. I have to hit the big red
switch to bail out.
Copying directories of this size has never been a problem with RH 6.1.
This is new to 6.2
NOTE: VM: is killing processes besides cp. It's killed bash and a
whole slew of others. Sometimes I've seen 6-7 processes killed at once.
# Problem 2 -- Memory leak
>From a *cold boot* I immediately log into the root shell. I run "top"
and it shows me:
mem: 63168K av, 12684K used, 50484K free, 8140K shrd, 1716K buff
Swap: 337324K av, 0 K used 337324K free, 6164K cached
I let the machine sit idle for an hour, never entering Xwin. When I
return "top" shows me:
mem: 63168K av, 61684k used, 1484K free, 508K shrd, 52348K buff
Swap: 337324K av, 2264K used 335060K free, 1036K cached
top itself is the largest process running at size:516, RSS:484,
Share:372
Somehow, while just sitting at idle for about 1 hour, the machine moved
around 50mb memory into a buffer.
This also happens in Xwin. When this memory is in a buffer, the
graphic performence is just abysmal. I move one window and it takes
the screen 45-60 seconds to redraw the screen. This is in Xwin running
a gnome session with one of the window managers I mentioned, but no
other user processes running besides a Gnome Terminal and GMC.
Again, this was never a problem in 6.1.
# Problem 3 --general weirdness
Sometimes when this is occuring, when I issue a "reboot -n" the system
will start shutting down services and then freeze in the middle of the
process, forcing me back to the big red switch.
I haven't seen anything like this on the list or in the archives. Any
help on this would be greatly appreciated.
