Stability problems with 5.3-Release

[Chris McGee]

I've got 2 identical boxes (Supermicro sys-6023P-8R) running with ZCR 
adaptec cards with 6 73Gig seagate scsi drives, 4 Gigs of ram, and dual 
2.4 Ghz Xeons.  Both of these machines are running 5.3-Release-p8.  The 
usually run for a day, give or take, and then they crash.  The just 
deadlock, no console response, no nothing.  The get power cycled and 
they are fine for a little while again.  These are configured to be 
mysql database servers.  I can provide any information necessary, but 
i'm stumped and it's causing me a lot of heartache now.
