[Ocfs2-users] Server hang after error

[Sunil Mushran]

Your config is sufficient. Hard to say why it did not reboot. Ping the debian
mailing list to see if there are reports of the same on whatever kernel you
are on.

As far as the reason for it goes, there should have been a message just
prior to the Kernel Panic message. Most likely reason is that it hit a on
disk corruption. I would suggest fscking the device.
