Definitely increase the hb timeout (O2CB_HEARTBEAT_THRESHOLD).

That's for starters. To figure out why it dies, I will need to see the
oops dump. But
my hunch is that it is hb related and that upping the default timeout
will solve that.
The second issue is puzzling. I'll try to investigate that today.

Hello all,
are there any issues concerning ocfs2 (v 1.2.3) and device-mapper-multipath-0.4.5-12.0.RHEL4?
I've build a 4 node cluster with two ocfs2 mounts on /dev/dm-0 and /dev/dm-1.
Under heavy load the nodes dies after about two minutes reproducably ;-(( Once
I've loaded the ocfs2 modules it seems to me that both modules
(device-mapper-multipath related as well as ocfs related) are affecting each
other. During the time of loading the ocfs modules there went some
multipath-paths away and came back again after completing the ocfs module load.
