Hi all.

Apologies in advance if my question has a somewhat obvious answer.

I'm working on a Zope application, developed as a python product.

I've ZTC in place for this application. While I run all the ZTC, I can see python process size growing. Can I use this as an indication of a leak of resources in my application?

Probably not. I suggest running your tests multiple times in a loop using the -N switch of the test runner. If the memory consumption grows with each repetition of the tests, you may have a leak.
