How do I know what an apache process is doing?

Solution 1
Make sure you have mod_status.so
loaded within your apache modules then look for/add the above to your httpd.conf:
# Uncomment the following lines to enable mod_status support:
#
ExtendedStatus On
<Location /server-status>
SetHandler server-status
Order Deny,Allow
Deny from all
Allow from YOUR_IP_HERE
</Location>
This will allow you to see all the pages being used load domain within your http server.
To access it use http://your_ip/server-status and only the ip defined at Allow from YOUR_IP_HERE
will be able to view it.
Solution 2
An lsof -p will show you what file handle it is waiting for. Also strace -p and ltrace -p might be handy to try to debug it.

Sometimes apache goes crazy and eats all my memory and swap, but I don't know how to find out which web app is the causing it.
ps gives me this output for the process; "Uninterruptible sleep (usually IO)"
www-data 1526 0.1 78.9 14928852 3191628 ? D Oct17 6:45 /usr/sbin/apache2 -k start
I suspect Ruby+Redmine, but I want to be sure
