Not that I know of. AFAIK this was in an automated security check that
was emailed to our 'admin'. I use that term somewhat loosely because we
don't truly have full ability to administrate this box - folks at MSU do
that. We have brought the problem up with them but they have found
nothing wrong. We see these messages and have problems with the box
crashing or needing reboots periodically (sometimes weekly and even
multiple times per week of late) which sounds very much abnormal.

I will attach dmesg though this time. I don't know right now whether we
can get the df -h or not. I'll check into it.


Thanks.
