1.2.1? That's 5 years old. We've had a few fixes since then. ;)

You have to catch the oops trace to figure out the reason. And one
way to get it by using netconsole. Check the sles10 docs to see how to
configure netconsole. Or, whatever is recommended for capturing the
oops log in that release.

The storage is a high end SAN and the transport is iscsi. We went two years without an issue and all a sudden node 1 in the cluster keeps crashing. I have never had to troubleshoot OCFS2, so I started with what I could control.
