[Ocfs2-users] Panic

[Laurence Mayer]

Hi again,

OS: Ubuntu 8.04 x64
Kern: Linux n1 2.6.24-24-server #1 SMP Tue Jul 7 19:39:36 UTC 2009 x86_64
GNU/Linux
10 Node Cluster
OCFS2 Version:  1.3.9-0ubuntu1

I received this panic on the 5th Oct, I cannot work out why this has started
to happen.
Please please can you provide directions.
Let me know if you require any further details or information.
