[Ocfs2-users] kernel panic - ocfs2-1.4.1 - redhat EL5 2.6.18-92.el5xen

Hi list,

We've just had a kernel panic/reboot on one of our ocfs2 cluster nodes.
It's a 3 node cluster of xen Dom U's running Redhat EL5.2, and
they're
normally very stable.

Has anybody seen this particular fault before, or can anyone provide an
analysis?

thanks

James Masson

Please file a bugzilla. Add this stack trace to it.

Also add any detail about your environment that you feel
could be relevant. Size of cluster, number of mounts, etc.

Thanks
