Clint, I appreciate your assistance with this but I am sorry to say that I believe I've wasted your time.
I did some intensive digging on this and discovered that all signs point to a hardware issue on one of the SCSI buses. MySQL appeared to be the "trigger"; with the most disk writes/reads. It looks as if a hard drive might be going south. I receive a fatal error message when attempting to run OpenBoot tests on the SCSI bus. Which, in retrospect, makes sense as to why occasionally I would experience a hardware hang on reboots every now and again as well as why a hard boot seems to be the only way to recover. Either way, my new system will be resolving these errors. Again, I appreciate your prompt responses and I apologize for wasting your time.
