[Zope] Tips in memory leaks esp with Catalogs?

[Dylan Jay]

Hi Everyone,

I have an application that gains a large memory footprint very quickly, in
casual testing 100M in an hour or so. I have a largeish ZCatalog with extra
PathIndexes, using Plone, Archetypes and various other custom code. Using
LeakFinder I get lots of BTree stuff from ZCatalog queries. It looks like
it's being created legitimately but what's keeping the references to them
and how to go about finding out? In the java world I would use a memory
profiler to follow the reference chain till it went where it shouldn't. Is
there such a thing for python? If not how does one go about working out
whats keeping the memory?
