[Ocfs2-users] OCFS2 1.4.1 DLM unhandled error

Tue Jun 16 04:44:28 PDT 2009

We have a 2 node OCFS2 cluster running Oracle 10g, both nodes crashed.

Node 1 because it panic running IOSTAT, the second node crashed with
this error message you can see below. 

I was hoping to see a newer version of OCFS2 so I could proceed with the
upgrade if necessary.

Have you seen this problem, anybody has resolved this?
