[Ocfs2-users] dlm timeouts and following errors -112

Hi list,

I am experimenting with ocfs2 (rpm package: 1.2.2-0.2), using linux-ha 2.0.8 
(all running on a SLES 10 x86-64, rpm packages from linux-ha.org) for the 
heartbeat. The three nodes are connected on a gigabit switch. From time to 
time  I have problems to unmount a drive, and I have to reboot the whole 
system to fix the problem. When these lockups occur, I see these messages 
in /var/log/messages:

I think it is because of the timeout at the beginning of the logs, but don't
know whether I am right, and what I can do to make it not happen anymore. Is 
there anything I can do to overcome these problems?

kind regards

Yes, the messages are related. -112 is EHOSTDOWN.
