Hi. Our CentOS 5.4 server just rebooted sponteneously while doing heavy I/O.
There is a message in /var/log/messages just prior to reboot,
kernel: Keepalive, Event:mdseve_cookie, client ping timeout
Google does not turn up anything. What does this mean and how can I prevent it from happening again, please?

P.S. I do have two kernel dumps from two reboots this morning. But I don't know how to read them or what to look for. Would appreciate any RTFM pointers.

I analyzed the two kernel crash dumps which told me we panic'ed while running rsync writing to a network filesystem.
I've upgraded our rsync from 2.x to 3.x and sent a copy of the crash info to our network filesystem vendor.
