Hello. I've encountered a weird problem and i don't know what to do. Few days ago I recieved another server to administrate. Machine had "some problems with memory". After some tests - i thought it was kernel fault - load was about 160; processes kscand and kswapd had very high cpu usage. After even more tests - i've find out that apache eats lots of memory (it's a 4 GB RAM machine + 4 GB of swap)... well it eats all avaible memory and wants more. Why? Comparing ps aux/top views with /server-status site, i've found out that the processes which are eating the most of the memory are those which are still open (and "sending reply") even that the most recent request was a long time ago (like 2000 seconds). Is it normal situation? Example: Srv PID Acc M CPU SS Req Conn Child Slot Host 10-1 5692 0/0/215 W 0.02 1006 0 0.0 0.00 1.87 66.249.65.36 PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND 5692 apache 15 0 286M 286M 6652 S 0.0 7.1 0:45 0 /usr/sbin/httpd Look at SS Value! Isn't it too high?! TIPS: 1) It usually happens if visitors are googlebot (as in the example above) or yahoo slurp! crawler (or similar). 2) For a first glance i thought it affects only one of my vhost sites, but after a while i see there are at least two of them (there is about 1200 vhosts). 3) I tried to reproduce such behavior and i made it. It is possible to enter URL from a webbrowser(which looks like that: $VHOST/index/oferta/wakacje/Francja/57365/Maeva_Planchamp_et_Mottet/Valmorel ) and after a while webbrowser has loaded site but on server-status page it looks like httpd is still "sending reply". 4) Server version: Apache/1.3.33 (Unix) Regards, -- Lech Karol Pawłaszek <ike> "You will never see me fall from grace..."
