Folks,
I have a RHEL 3 production Cyrus IMAP server that has kernel paniced
twice in as many weeks with something similar to the below. The /imap
partition (where the IO was in question) is about 98% full with about
6.2G free and is hosted on a fiber connected EMC Clariion lun.
Currently running kernel 2.4.21-15.0.4.ELsmp.
I know things are old here, and the machine is on the upgrade list, but
I need to do due diligence to figure out how serious this error is.
Does anyone have any advice why this is happening?
Thanks,
Jack Neely
