Without having the answer you may want to expand on if 'Restarting the server' means rebooting or web server restart, i.e .../httpd restart. Also, when web server slows down does a local 'lynx IP-of-interface' behave the same? Would a frequent cron job be able to detect, e.g. huge amount of httpd children, or other odd symptons,... and then call the reboot or httpd restart? --there may be symptoms visible before the slowdown reaches the extreme. Certainly an every 15 min cron job that calls a logging script with """ ... logFile='yourChoice' echo ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ >> $yourChoice date >> $yourChoice echo ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ >> $yourChoice pstree >> $yourChoice echo ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ >> $yourChoice ps -Afl >> $yourChoice echo ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ >> $yourChoice top -b -n 1 >> $yourChoice echo ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ >> $yourChoice ...etc """ would help with the diagnostics (but don't let it grow out of control) - Horst Date: Fri, 13 Dec 2002 13:34:21 -0800 (PST) To: [EMAIL PROTECTED] Subject: Re: [Eug-lug]Use perl to monitor webserver? ... I forgot to mention to look at the other cron jobs cron.daily, etc. included, and start the diagnostics log a minute AFTER those. That way you see which processes hog which resources. cron.daily can get quiet busy.....................
