Re: [users@httpd] Why so many apache processes?

Hello,

Look back at your config. It says 5 threads minimum, so at elast 6 processes are spawned when apache is started : the main process and 5 childs. Your config says 50 max, so at maximum there would be 50 threads... Normally, there's another config option that states how many threads are started at startup (in apache 1.3 at least..) so that's why there is a certain number of childs that are started straight... (18 in your case) It's better, anyway, because in case of a peak the system will be ready to answer a lot of requests. If you don't want that many processes running, just lower your maxSparesTHreads

Hello,

On aLinux system I have an Apache, with multi threaded worker, and the
following in the conifg:

<IfModule worker.c>
StartServers         1
MaxClients         50
MinSpareThreads     5
MaxSpareThreads     50
ThreadsPerChild     5
MaxRequestsPerChild  100000
</IfModule>

Just after having started though I notive quite a few processes:

Why is that? I would have expected only two: The main process, and one
child. The server is serving no requests, so should not be spawning
additional children.
