Upgrade to OCFS2 1.2.9-1 shipping with the latest SLES9 SP4 kernel 
(2.6.5-7.312).

You are most likely hitting bug#6680001 as mentioned here.

Also, you might want to tone down the heartbeat threshold from 10 mins
to 1 or 2 mins.

If you still have problems, log a bug with Novell. We may need more details.
