Even cleaning > personnel is known to cause reboots ;) True. So very true!

Then, in "Post-Mortem Analysis of a Dump" you'll find out how this dump can be used to debug the crash. -giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
