[CentOS] Checking what's running inside a httpd process

Also, a thing I've notice is that httpd process tend not to relase it's
used memory very fast. So if you see that the process is not doing much (via
server-status), you can safely kill it. The parent httpd process will create a
new one when needed.

> I'm trying to fix a CentOS (5.5 x86_64) VM that we have where it become
unstable due to swapping. But I did notice something: I have 10 httpd processes,
and 5 of them are using 13 MB of resident memory, the other are using between 91
and 96 MB of RAM. I find it quite strange to see such differences in RAM usage.
I ran a "lsof -P -p" on the processes, and I didn't see any major
differences, so I'm wondering what is the best way to know what the
processes are doing?
