Apache2进程永无止境 - 我如何确定原因？

Question

So I just set up a new VPS, and as soon as I turn it on (MaxClients set to 140) maxclients will be reached, and apache processes don't stop ending until they reach timeout (15 seconds).

How can I further debug this to determine why they're not ending?

Unfortunately it's a production box, which is why maxclients is reached so quickly after an apache restart.

I'm running Apache 2.2.16 on ubuntu 10.10, kernel 2.6.18, and PHP 5.3.3

MySQL is running on a separate server (Note: I have a hunch that maybe the processes aren't ending due to something MySQL related, but I'm not sure what to look for) In the past I had MySQL/PHP on the same server and everything was fine, since I've moved to 2 separate I've been running into this issue.

Answer 1

Curl was being called on multiple pages and there was no timeout set, so it went to max execution time.

I've since fixed! strace -p is a life saver!
