JP, We use to have a similar problem with an older version of Red Hat Linux. However, the two culprits were the SCSI controller failing (the servers had run for about 35000 hours, hard, and also through intense heat) and RAM going bad. There is a application that is safe to run on your machine, if you can afford to take it offline for a while. The program is called "The Troubleshooter". I recommend it and some of the big computer builders use it to do burn-in tests.
