Finding memory leaks is an exercise in binary search. Isolate half of the Zope (and Product) code and find out if it leaks. If it doesn't, you know the problem is in the other half. ;-) Ad infinitum. I'm sorry this is the case, but it almost always boils down to this particular recipe of

It's not covered by the data output into the -M log. Objects can leak without requests hanging or taking a long time. But you might be able to turn on profiling (set the PROFILE_PUBLISHER env var to a filename and restart Zope) on a *test* box (do not do it in production, it drastically

In either case, it seems like you shouldn't be using ParsedXML's ExpatBuilder, which is an interface to PyExpat which is made to create ParsedXML's DOM objects. You should be using your own PyExpat interface to parse this information from your XML input, without the overhead of generating a
