Consider a backup, reformat, restore on the drive. It sounds like you may have subtle corruption on one of the partitions ... but then agian, why would it work on one machine and not another? > I have run a hardware check program (memory, HD, cpu, etc..) and no errors > found. For how long? If the problem is intermittent, running the HW check while the problem is not occurring may not reveal anything. Can you afford to take the machine offline and run the HW check for an extended period?

Could also be a power supply. If you have spares, try swapping. > Is there any debug mode on FreeBSD so I can let if log all activity and > see what the machine was doing when it froze?

Well, they aren't "good" suggestions, but they certainly fall under the category of "any". I hope they're helpful. -Bill -- If a bird in the hand is worth two in the bush, then what can I get for two hands in the bush?
