... When you fixed the TempStorage the leak indeed slowed down significantly. However, Zope still leaks memory. If left uncheck Zope will still consume all available memory and crash the server. We have resigned ourselves to restarting Zope every few weeks.

Looks acceptable, doesn't it? Such "leaks" can be caused by so called memory fragmentation. Memory fragmentation describes the situation where the available free memory is spread over large amounts of small blocks. When you need a somewhat larger block, then a new large block is requested from the OS and cut down into smaller pieces. Thus, this block, too, may finally end up as a set of small blocks. Memory fragmentation is something like the entropy increase in the world... Restarting gives you a new world with small entropy... -- Dieter
