Httpd process using all cpu time

[Anon]

I have been recently noticing strange Httpd thread that are using all the cpu and seem to run forever, here sample output from the top command(I ran just now) :

%CPU %MEM TIME COMMAND
45.6 0.0 346:52 httpd
45.2 0.0 317:11 httpd

These are slowing down the site incredibly and I have to restart apache when I see them.

When I posted on another forums someone said it could be an infinate loop somewhere but how can I track this other than going through all the code. Should't scripts have some sort of maximum execution time anyway?

Of course this problem could not be due to php but it's the only scripting language I use.

If anyone has any suggestions I would be most gratefull.

Well it set to 30 seconds so that can't be it, i've seen these process's run for 5 hours or more while consuming all available cpu power.

Maybe it isnt a php problem but I am totally lost on what it could be.
