If they do go away then we know where to look and might have a better chance tracking down the problem. So far I haven't been able to make heads or tails of your crashes... it's like something is randomly corrupting memory. My best hope was that the UPAGES fix would solve the problem but it seems that it hasn't. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
