when I detect an "offending" process (using too much memory), it's

The real answer is to locate the bug. If you really want to do that,
build/install debug versions of your s/w, attach gdb to the running
process, and ask for a backtrace.

Update : 

Just to let you know, we
use proxying to serve http://requests/like/that to customers while
internally getting http://requests?like=that if you see what I mean

Could it be the source of a problem ?
