It probably means one of: 1) Your processor is overheating. We had a dual PIII 600 which came with fans which weren't up to the job and them machine would lock up after a few minutes. 2) Your motherboard is sick. We had a motherboard which was causing every 8th byte of a 4k page to be corrupted once every few weeks. The new version of the MB had added a heat sync to the memory controler, and works perfectly. 3) Your memory is sick. Don't trust the BIOS test - I've seen SIMMs pass the BIOS test that have a blob of solder stuck across a few pins on the ram chips. The only way to find out is to swap parts until the machine becomes stable. David. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
