And to point out that I'm not being obtuse, here is a snippet from
http://oss.oracle.com/bugzilla/show_bug.cgi?id=822 :

Environment:

Linux x86-64 Redhat 4.0 Update 3
OCFS2 1.2.3 3-node cluster.
Problem:

After installation, created two filesystems to be used for software. To limit timeout problems, increased the O2CB_HEARTBEAT_THRESHOLD TO 31.

During maintenance window, decided to use the OCFS2 filesystem to store a large backup file (about 5-10 gig file). SCP'ed the file from an outside server to node1 of the cluster using command "scp $file oracle_at_sachlp10:/ocfs2_fs1/.

After a few minutes, node1 crashed.
Did not find error messages on node1, but found them in /var/log/messages

on node2:

...wow, sounds like a pretty aggressive workload, right?
