well, I would speculate that your /etc/periodic is running @ 3am doing things like looking for setuid files, pruning /tmp, etc, which sparks up some disk activity, forks a few processes, walks the filesystem, etc, which is tripping some=20 bug you have in the kernel, or bad memory. [i have a version of memtest86 which can be loaded from 'loader' and placed on a fbsd file system if you wish to try the bad memory theory conveniently]. I have a similar problem in 4.7 that occurs once in a while @ 3:01am which seems to randomly corrupt memory. I've been chasing it for a while but is hasn't been reproducible enough to find. This is pure speculation. man 8 periodic see /etc/periodic.conf > -----Original Message----- > From: Dennis Pedersen [mailto:mlists@daydreamer.dk] > Sent: May 28, 2003 16:46 > To: Don Bowman; freebsd-net@FreeBSD.org > Subject: Re: Spontan reboot of FreeBSD 4,x box >=20 >=20 >=20 > ----- Original Message ----- > From: "Don Bowman" <don@sandvine.com> > To: "'Dennis Pedersen'" <mlists@daydreamer.dk>;=20 > <freebsd-net@FreeBSD.org> > Sent: Wednesday, May 28, 2003 3:56 PM > Subject: RE: Spontan reboot of FreeBSD 4,x box >=20 >=20 > > > From: Dennis Pedersen [mailto:mlists@daydreamer.dk] > > > > > > I have a couple of FreeBSD 4,4 and one 4,7 that are beeing > > > used as firewalls > > > in different locations. > > > Lately i haven noticed that one of the firewall's was > > > starting to reboot at > > > a certin time of the day (give or take maybe 10min). > > > > The time it resets wouldn't correlate to the periodic (e.g. > > 3am) would it? >=20 > On one of the box=B4s that fits yeah.. > What am i missing? > cron_enable is set to no in rc.conf and the cron deamon isnt running? >=20 >=20 > Regards, > Dennis >=20
