Subject: Re: Multiple httpd processes?

Firstly, no need to be concerned, this is just as it should be.
When apache is started the process (2902 in your list) spawns a number of
child processes. These are the ones which actually serve up pages. 2902 is
simply passing requests out to the next available child. By doing this the
system can serve multiple requests simultaneously, which on a system which
gets lots of hits improves performance no end. You can tweak the httpd.conf
file to adjust how many of these children get spawned, but to be honest,
unless your system is very slow I'd not bother.
Hope that answers your question
Pete
