Over the course of the last four to six weeks, my system has been crashing unexpectedly (and of course, when I'm not home to coax it back to life). Today, it died, and rebooted itself, though not a soft reboot (like it used to do occasionally) -- it was a hard reboot... The last thing that is written to syslog() when it happens is messages like: Sep 21 17:00:00 shasta CRON[925]: (root) CMD (/usr/libexec/atrun) This system runs a plethora of daemons -- xntpd, named, sshd, httpd, ftpd, rwhod -- am I merely overloading it? Or is there some bug in at/atrun? I have coredumps enabled but have not yet seen anything in /var/run/crash from it. Should I just rebuild the world? (I'm going to anyway, and see if that helps). And, no, the power has not been out here today. (Other system is running just fine, and is identical except runs stock 2.1.7.) More information on request; not sure exactly what to send along with this. Here is some syslog() info; it has been edited to exclude the xntpd, named, and sendmail stuff. If you wish to examine the whole chunk from today, I'll have it available at ftp://shasta.wstein.com/pub/system/log.970921 (it's a *.* log so it's huge.) in short order (by the time you read this message.) Thanks for any help!
