 Posted: Fri Feb 16, 2007 12:30 am Post subject: Lighttpd Questions about FastCGI |
 |
|
I have lighttpd installed on a server, gentoo 2006.1, kernel 2.6.20, amd64, php5, mod_fastcgi. Every so often, the fastcgi processes (I have 30, with no adaptive spawning) drop in cpu usage to less than the top window I'm using, and then about 5 seconds later, all 30 spring to life (about 70% cpu each), and then it settles back down to the normal 4-5 active php-cgi processes(having any cpu load).
Thi site lags for these few seconds. I haven't discovered why this is occuring, I thought it might be adaptive spawning, but I set max-procs == min-procs, therefore disabling active spawning, and the issue still occurs. While it is only occasionally, it is a marked lag during these periods that I would like to eliminate.
mod_fastcgi.conf

If anyone has any ideas, it'd be much appreciated.
Thanks,
