When this message started appearing again (now with the PMAP_SHPGPERPROC set to 300 in the kernel config file) I took a look at the system and what it was doing. I was very disturbed to find that according to 'ps' pagedaemon was eating up 67% of the cpu. This is a dual-PIII 500 machine, and I'm not sure if 'ps' is reporting 67% of one CPU (my first guess) or 67% of both. I captured the output of 'ps -aulx' to a file, here is the bit about pagedaemon, line wrapped for readability. USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 2 66.7 0.0 0 0 ?? RL 10:12AM 5:15.52 (pagedaemon) UID PPID CPU PRI NI WCHAN 0 0 265 -18 0 - There were no other unusual symptoms, except that the miva (CGI) processes that the box is supposed to be processing were backed way up. Normally they complete very quickly (roughly 3 per second) with little or no backlog. I've increased the PMAP_SHPGPERPROC setting in the kernel config file to 400 and recompiled just in case the system panics again, however with it set to 300 as it is now it recovers ok. Once again, any thoughts or suggestions welcome. Thanks, Doug To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
