If i understand the man page of periodic correctly then it should'nt run if cron is'nt running? (ps aux |grep cron gives nothing and cron_enable is set to 'NO' in rc.conf) Can i simply remove the scripts from daily to make sure nothing is running from there or will that possibly crash the box? (i dont have access to the box with anything other than ssh right now.) Memory i having trouoble beliving in , its 3 different box's. 2 running 4,4 and one running 4,7. All on different hardware (except the nics are 3com, not same model.)

[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 > > > > ----- Original Message ----- > From: "Don Bowman" <don@sandvine.com> > To: "'Dennis Pedersen'" <mlists@daydreamer.dk>; > <freebsd-net@FreeBSD.org> > Sent: Wednesday, May 28, 2003 3:56 PM > Subject: RE: Spontan reboot of FreeBSD 4,x box > > > > > 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? > > On one of the box´s that fits yeah.. > What am i missing? > cron_enable is set to no in rc.conf and the cron deamon isnt running? > > > Regards, > Dennis >
