Description Hallstein 2006-01-31 01:06:33 UTC 
Most recent kernel where this bug did not occur: (unknown)
Distribution: CentOS release 4.2
Hardware Environment: Dell PowerEdge 2650
Software Environment: NFS/SMB Server (samba-3.0.10-1.4E.2)

Problem Description:

We've encountered Kernel Panic in lockd (nlmclnt_mark_reclaim) several times 
in the last months. This seem to be related to heavy usage on server. 

The server runs Samba export of NFS imported (and local) filesystems. 

A picture of the panic is here:

After this panic, the computer stops responding, and we are forced to reboot 
the computer.



Steps to reproduce:
Seem related to high load, but otherwise difficult to reproduce.

I think your kernel is a distro kernel. Not a kernel.org one. If that is the
case, please file a bug with the distribution. If you can reproduce the same
situation with 2.6.15, or 2.6.16-rc1, it is more likely we could help. Presuming
this is a distro kernel bug and you are unable to reproduce it in a more recent
kernel.org kernel, I'll close the bug.

Thanks,
Nish

ive posted the bug at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?
id=179545 and I hope redhat will look into it.  The bug *might* be related to

This bug has also been seen on newer kernels and reported on LKML. I'm still in
the process of tracking it down.

Any updates on this problem?
Hallstein, have you tested with newer kernels?
Thanks.
