Hello, Yup, that's right, my Zope is leaking memory, and so far, I've had no luck figuring out where it might come from. I run a Zope 2.5.0 on RedHat 7.3. I started by looking into the Python/C type modules, which I fugred are most likely to be causing this. I upgraded Psycopg to the latest version, but it's still occuring. I also use the PIL, but it is seldom used, and could not be the cause of the kind of leakage I'm seeing. Then there's a much more obscure thing, which is a SWIG interface to PROJ.4 (A geographical projection library) ... I had the author look at it, and no leaks were detected in the C library, or using the SWIG interface (Using Valgrind I beleive). My Z SQL Methods do NOT cache results (Maximum time set 0). (...) Any ideas, comments, insights, tips would be MOST appreciated! Thanks in advance, Jean-François Doyon
