Good evening, folks...
We have been experiencing a very rare (on average once every two to
three months) crash on some of our servers.
uname -a:
Linux cheetah 2.6.9-22.0.1.ELsmp #1 SMP Thu Oct 27 13:14:25 CDT 2005
i686 i686 i386 GNU/Linux
(This is a CentOS provided kernel)
Here is a photo of the bottom of the panic. Unfortunately the kernel has
no chance to log this anywhere else:

The crash appears to be in prune_dcache, and has happened on several
distinct machines, so we do not believe it is a hardware problem.
If anyone has pointers on what bug could be causing this crash, or if
it's been fixed in newer kernels we could try, it would be greatly
appreciated. This only seems to happen on loaded production machines,
and it happens so rarely that more detailed debugging is nearly impossible.
Thanks in advance,
-John Flynn
