Is it possible to reproduce the issue when launching TB on the machine locally?

Didn't succeed in any of my following attempts to reproduce this issue: - run TB from NFS exported ~home a x86_64 client for a few days on OpenSUSE 10.2 - run IOZONE in mmap mode on NFS mount point - a test program which was originally written to test NFS mmap consistency Could you enabled NFS client-side debugging by doing: echo 65535 > /proc/sys/sunrpc/nfs_debug and report the nfs debug messages (from /var/log/messages) when it crashes? Also, any pointers to what could(operation) trigger this crash or any way to reliably reproduce the issue would be helpful. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

However, the following mm patch - http://lkml.org/lkml/2007/1/29/180, has been included which probably could have fixed this issue not sure, though. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It looks like a reboot helps, so the update was probably irrelevant. Perhaps it depends on how much memory is used or something like this. At the moment I have 4 identically configured boxes and it works on one of them (segfaults on the others). Still investigating. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Rafael: By any chance, did you happen to hit this issue with OpenSUSE 10.3 as well?

No, I haven't installed 10.3 on these boxes yet.

Haven't had much luck in reproducing this issue or getting enough clues.

I understand.

Enabling Client-side debugging before it crashes as mentioned in Comment #4 could help a bit.

Well, I didn't have enough time to investigate the issue more thoroughly. I'll probably try to install a new kernel.org kernel on one of these boxes and see if that helps (modulo other problems that may appear as a result). Please keep the bug open, as the issue is still present, AFAICS, but I'll let you know when I have more information.
