Why ignore /proc over the System.map? The system had very little running (because of prior lockups) during the morning SQL activity. About 3/4 of a megabyte was being added to the SQL databases, and that activity had been going on for 45 minutes prior to the oops. No X, and I was reading email as the only other load. Daemons: postfix, raid5, xntpd, syslog, cron & kernel. SMP kernel, built with gcc 2.95.3 released 20010315. At the time of the oops, there is an cron task that feeds postfix, which deposits the email into a 3 meg file. ------------------------------------------------------------------ ksymoops 2.4.1 on i686 2.4.5-ac12.
