This happens on all nodes. The CPU# and timestamp change, but the
problem persists. The systems do not restart or panic. The system
merely puts every process accessing the OCFS volume in a D state.
Would you still like me to log another bugzilla issue? I am happy
to do such if you wish.
Cheers,
Matthew

A bugzilla with the oops stack trace will help.

Greetings, I am looking for a good way to diagnose random crashes
that are occurring with one of our OCFS clusters. It is a simple 2
node cluster. debugfs does not seem to indicate any issues.
(Also, I would be happy to find a consultant/freelancer to work
through this.)
Cheers,
Matthew
