kernel oops on debian , 2.6.18-5

[Yann Dupont <Yann.Dupont@univ-nantes.fr>]

Hello, we got a kernel oops, probably in xfs on a debian kernel.

This volume is on SAN + device mapper.
this is a 1 TB  volume. It was in service for more than 2 ou 3 years. 
There is a high humber of files on it, as this volume serves for a 
rsyncd, where 200+ servers sync their root filesystem on it every day.

here is the oops :

rectify the problem(s)

and the kernel  :

inchgower:/var/log# uname -a
Linux inchgower 2.6.18-5-vserver-amd64 #1 SMP Fri Jun 1 00:27:03 UTC 
2007 x86_64 GNU/Linux


Please note that it is not the "generic" debian kernel, but the vserver 
one - but stock etch version anyway. We had not seen any problems with 
this combination, (xfs + debian kernel-vserver) which is very largely 
deployed here. This is a first.

Do you think the problems is due to xfs or other factors ?

Sincerely,
