Moreover, eventually (in a few hours) the server appears to lock-up. However I can't say for sure if the lock-up is related, or what messages appear during that time, as this is a remote system with no IPMI or the like. There's nothing in disk-based logs. I'll try netconsole later if this continues to repeat. For now, any ideas about this particular backtrace?
