Zopists, I use Zope 2.1.1 in a production environment where my ZODB is about 300MB. It gets up to about 1500MB by the end of the day. I have 25 people using it constantly 10 hours a day, everday, 6 days a week and I never shut it down. My Control Panel says this: Zope version: Zope 2.1.1 (binary release, python 1.5.2, linux2-x86) Python version: 1.5.2 (#10, Dec 6 1999, 12:16:27) [GCC 2.7.2.3] System Platform: linux2 Process ID: 5439 (8201) Running for: 23 days 15 hours 14 min 51 sec My sys-admin restarted Zope by accident 23 days ago. If there was a memory leak I probably would have known about it long before now. I have 10 threads going, in case anyone was wondering. I just want to say that I think Zope is a quite a terrific piece or open-source software. For all that it provides, it's stability is remarkable. If anyone needs a testimonial, as you can tell, I'm not shy about how I feel about Zope.
