Hi folks, I have a problem with apache/PHP config, and for hte life of me cant find a solution in google or on the apache website. Basically when apache spawns a child process, and the process completes its work, it is not dying. This means that in the timespan of maybe 20 minutes, my apache server hits MaxChildren and grinds to a shuddering halt. Restarting the server then resets it, and the cycle starts over. This is driving me crazy. For those who need full information, a more detailed description appears below. Servers : Distro : Centos 5.2 Kernel : 2.6.18-53.1.21.el5 #1 SMP Tue May 20 09:34:18 EDT 2008 i686 i686 i386 GNU/Linux apache version : Apache/2.2.3 (CentOS) php version : 5.2.6 while watching the server-status page from the server, it appears that most of the processes are in state 'w' : "W" Sending Reply, 3.61 requests/sec - 12.2 kB/second - 3450 B/request 61 requests currently being processed, 5 idle workers KWWW.WWWWWWW_WWWWW_WWW_WWWWWWWWWW.WWW.WWWWWWWWWWWWWWW.WWWWW_WWK. W..W.KKW_..W.................................................... ................................................................ ................................................................ then a short time later .... 3.54 requests/sec - 12.4 kB/second - 3581 B/request 99 requests currently being processed, 5 idle workers KWKWWWWWWWKWWWWKWWWWKWWWWWWWWWWWWWWWWWWWWWWWWWKWWWWWWWWWWWWWWWWW KWWWWWKWWWKWWWWWWWWWW_KWWWWWKKWKWKWK____........................ ................................................................ ................................................................ as you can see, the requests per second went down, but the number of processes in wait state went up. Obviously this is a bad thing can anyone help me here, or even point me in the right direction ? I am running apache-prefork with the following conf snips : <IfModule prefork.c> StartServers 10 MinSpareServers 5 MaxSpareServers 10 ServerLimit 256 MaxClients 256 MaxRequestsPerChild 15 </IfModule> I have also set the apache timeout to 20 seconds, and the keepalive timeout to 2 seconds. However,I have a process that has been alive for 1759 seconds. Even the PHP timeout is set to 15 seconds. I have even gone as far as setting /proc/sys/net/ipv4/tcp_fin_timout to 5 seconds in an extreme attempt to get things to play nice ... nothing seems to be working and I am getting short on heair to pull out ... thanks for anything :) Richard -- ref <tbs-Gb/NUjX2UK8 at public.gmane.org>
