Matt, more on this one.... Our server crashed again today. Even after backing off from -stable to 4.5-P5. Sysloging to another server did not work, the box must be just that brain dead, however, it was the same exact error on the console and oddly enough, around the same exact time of day. The box has only been up 1 week, 1 day. Both times the box has crashed crashed at ~3:02am. I'm thinking that something in periodic daily is causing the crashes. Keep in mind, that this server serves several NFS clients which mount things such as FreeBSD ports and /usr/src. Those are soft linked to on the clients to the NFS mount locations. All of our clients are FreeBSD-4.5, all synced via NTP broadcast. Could it be that all of the servers are all thrashing the NFS box for some reason when periodic runs? ... Scratch that, I just checked and all the other servers daily runs seemed to have run fine, I got all of their daily output. Seems to run fine for a week, and I've never really watched the box at 3:01am when periodic daily runs. I've changed periodic around on the NFS server (before the crash) and got rid of quite a few things. # Daily # daily_clean_rwho_enable="NO" # Delete rwho daily daily_backup_aliases_enable="NO" # Backup mail aliases daily_backup_distfile_enable="NO" # rdist /etc/Distfile daily_accounting_enable="NO" # Rotate acct files daily_distfile_enable="NO" # Run rdist daily daily_news_expire_enable="NO" # Run news.expire daily_uuclean_enable="NO" # Run uuclean.daily daily_status_uucp_enable="NO" # Check uucp status daily_status_rwho_enable="NO" # Check system status daily_status_mailq_enable="NO" # Check mail status daily_status_mail_rejects_enable="NO" # Check mail rejects daily_queuerun_enable="NO" # Run mail queue # Weekly # weekly_clean_kvmdb_enable="NO" # Clean kvmdb weekly weekly_uucp_enable="NO" weekly_locate_enable="NO" # Update locate weekly weekly_whatis_enable="NO" # Update whatis weekly And the box still crashed. Still interesting that it crashed. -- Robert Blayzor, BOFH INOC, LLC rblayzor@inoc.net (A)bort, (R)etry, (I)nfluence with large hammer? > -----Original Message----- > From: owner-freebsd-stable@FreeBSD.ORG > [mailto:owner-freebsd-stable@FreeBSD.ORG] On Behalf Of Robert Blayzor > Sent: Wednesday, May 29, 2002 9:03 AM > To: 'Matthew Dillon' > Cc: freebsd-stable@FreeBSD.ORG > Subject: RE: Swap_pager error > > > Hi Matt. > > I ran your suggested tests on this today.
