OK, well, there are some indicators you might follow. Is this reboot happening nightly at the same time? There was a cron job running find at the time. What filesystem types do you have mounted? Have you got anything odd (loopback, union, ntfs) there? Is there a half-formed mail sitting in a queue somewhere indicating which jobs were running at the time? Can you force a crash manually by going through the nightly, weekly, monthly periodic jobs? jan -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 RFC822 jan.grant@bris.ac.uk and Nostradamus never dreamed of the Church of the Accellerated Worm To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
