I am running OEL 6.4 (a RHEL clone), and rsyncing large files over ssh nightly. During the rsync, I regularly (most nights) get a kernel panic:

kernel:Kernel panic - not syncing: Fatal exception
Is there any information in the above that might give me a clue to the reason or is it all generic? There appears to be nothing unusual in /var/log/messages
at the point of the crash.
edit:
I should have mentioned I'm using ocfs2 (local not clustered). The files being transferred are the backing files for VMs and they are not in use at the time of the transfer: they are 'reflink' copies taken purely for the purpose of the rsync. The OS is up to date with patches.
