So this happens reliably, but infrequently? (only every 2 weeks or so?)

Can you provoke it any more often?

That's a RHEL6 kernel; I'm assuming that this is a RHEL clone w/o RH support?

I agree with Ben that I'd like to see xfs_repair output.

Since the fs has shut down, you should unmount, remount, and unmount
again to replay the dirty log.  Then do xfs_repair -n, and provide the output
if it discovers any errors.

Thanks,
