The RAM is ECC. Well, this is definitely not an application problem. Your kernel panics before the malloc data for allocated/free memory is corrupt somehow. This seems to be a hardware problem. Namely one of your memory chips playing tricks on you. I would start by removing a few RAM chips and seeing if this happens when a particular set of them are being used. If the problem persists but only when a certain chip is present, you know whats wrong :) -giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
