I commented about this a day or few ago, but at that point I was still chasing other possibilities, so here I go again 8) I have a reasonably -curent system that, under moderate load is dying after about 18-20 hours of uptime. The system itself is a P120 on a Triton board with 64M and an NCR PCI controller : FreeBSD mstradar.esrange.ssc.se 2.2-CURRENT FreeBSD 2.2-CURRENT #0: Mon Jul 15 13:16:26 MET DST 1996 msmith@spore.atrad.adelaide.edu.au:/usr/work/radarsys/compile/MSTRADAR i386 The system is being pushed fairly lightly, although there are some long-lived processes that accumulate a lot of CPU (and have largeish swap footprints). These large processes are all Linux a.out binaries (IDL). Symptoms are that the system remains pingable, and you can often get through the telnet login sequence to the point where /usr/bin/login is invoked but no further. As I type, the system just died under me again; I was watching the output of 'systat -vmstat', quit and typed 'w' to check the load. I got this : mstradar:/home/radar>w 5:04AM up 19:28, 2 users, load averages: 0.00, 0.00, 0.00 USER TTY FROM LOGIN@ IDLE WHAT and then nothing more. There have been no console or syslog messages to date from any of the times that this has happened. Any suggestions as to where to start looking would be appreciated; unfortunately due to the rather remote location of the system I can't play DDB with it 8( Help? -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
