Just updated to ia64 r205248
If my problem is due to my mis-configuration,
I apologise in advance.
I run this shell script after each upgrade
and 'make delete-old-libs' to check
if any shared objects need to be rebuilt:
<start script>
#!/bin/sh
for file in `find /bin /sbin /usr/bin /usr/sbin /usr/lib /usr/libexec /usr/local -name
"*"`
do
echo $file
ldd $file >> /root/ldd_results 2> /dev/zero
done
<end script>
This will probably do closer to what you actually would want to look for.
Writing to /dev/zero ... I don't know never tried it since /dev/null is
usually the standard place to throw trash.
#!/bin/sh
for file in `find /*bin /usr/*bin /usr/lib* /usr/local/*bin -type f` do
echo $file
ldd $file >>/root/ldd_results 2>/dev/null
done
The problem with your script is that it finds most files that it can not
or is not useful to run ldd on and leaves you junk in return.
It might be more useful if you searched for dynamically linked ELF
binaries to run ldd against like the following.
=== Script starts here ===
#!/bin/sh
SEARCHPATH="/*bin /usr/*bin /usr/lib* /usr/local/*bin"
trap 'exit 1' 2
check_libs() {
for spath in $SEARCHPATH; do
for ifelf in `find $spath -type f`; do
ldd `file $ifelf | grep dynamically | cut -f1 -d:`
done
done
}
check_libs 2>/dev/null
=== Script ends here ===
The above will find all type ELF * that are dynamically linked within the
SEARCHPATH variable and run ldd on them and print the results to stdout.
Obviously since you are going to have thousands of files being questioned,
stdout is not going to be useful.
So with the about stated:
save the script to: checklibs.sh
run with: "sh checklibs.sh >/root/checklibs_output"
or: "script /root/checklibs_output checklibs.sh"
After the upgrade to r205248, the script
freezes at seemingly random points.
Unneeded disk usage & execution.
I can still ssh to the machine (using keys), i.e.
I see the welcome message, but cannot get to the console prompt.
Of course... to many open files or processes in wait. SSH already has the
information it needs loaded into memory, that's why you can get sort-of-in
ZFS file-system perhaps ?
I've no ZFS.
I'm seeing very similar behaviour now with csup:
( I do csup -L2 /root/ports-supfile, where
# cat /root/ports-supfile
*default host=cvsup.uk.FreeBSD.org
*default base=/var/db
*default prefix=/usr
*default release=cvs tag=. delete use-rel-suffix compress
ports-all
# )
top(1) shows:

which stays in biowr state indefinitely.
I can issue kill -9 or kill -HUP from top(1),
which makes csup change state to STOP, but
nothing else happens.
As before, I can't log in from other terminals
and have to do a cold reset. I've reinstalled
on another disk, so not sure what's going on.
I think rm(1) is also extremely slow, but
maybe I'm imagining things.
many thanks
anton
I would post up the contents of your make.conf & your kernel config & your
dmesg somewhere so it can be evaluated.
