(resending due to size , sorry mods)
Hi ,
After moving to linux 2.4.31 and openafs 1.3.83 , I still get
oopses once per day. Usually this causes the system to either freeze
totally (only replies to ping) or all processes segfault. Exacly the same
happened with 2.4.29 and 2.4.30 with openafs 1.3.82. With openafs 1.3.78
the oopses occur usually after 10+ days uptime (dunno with 2.4.31 yet
though,running it now)
My cell consists of one 1.2.x server with the openafs database and
one 1.3.x server , for large files support. The volumes I access are on
the 1.3.x server. All servers are running gentoo linux , the 1.3.x
2.6.11.6 kernels and the 1.2.x 2.4.27. My system is a dual p3 @ 600 Mhz
with 768 Mb ram. I have just memtested the system , in completed
several passes and no errors were detected. The cpu temperature is ok , I
also checked thedisks. Without openafs running the system is stable in all
stress tests.Running slackware 10.1.
The problems always occur after 4 am , sometimes exacly at 4 am
sometimes one hour later. At 4 am my afs servers restart themselves.At the
same moment usually there are tenths of concurrent read/write operations
on my volumes. However I have not succeeded in reproducing the oopses
while manually performing fileserver restarts with processes writing to
afs.
First , the ooposes with 2.4.31 SMP and openafs 1.3.83
ksymoops 2.4.11 on i686 2.4.31. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.31/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

The complete log can be found at http://tassadar.physics.auth.gr/~dzila/oops1
oops with non-smp 2.4.31 and openafs 1.3.82 follows :
ksymoops 2.4.11 on i686 2.4.31. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.31/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
