Detecting memory leaks on apache, mod_python

[Ilias Lazaridis]

How to detect memory leaks of python programms, which run in an
environment like this:

 * Suse Linux 9.3
 * Apache
 * mod_python

The problem occoured after some updates on the infrastructure. It's
most possibly caused by trac and it's dependencies, but several
components of the OS where updated, too.

Any nice tools which play with the above constellation?

Thank's for any hints!
