Hi all,
I'm sure this question has been asked before, but it drives me nuts so I
figured I'll ask again. This is a problem that has been bugging me for
ages. Why does zope memory use never decrease? Okay, I've seen it
decrease maybe by a couple megabyte, but never by much. It seems the
general
Several years ago, we added a "tid" cache, that cached current
ttransaction ids (tids) for objects. The intent was to speed both
stores and full cache verification. We've since realized that full
verification is a bad idea for databases large enough that caching is
needed. It's not clea
There was a recent modification to limit the ZODB cache to a set size. i.e.
Limit the size of memory usage to 128MB.
The original feature was implemented here:
http://svn.zope.org/ZODB/branches/dm-memory_size_limited-cache/
You can get the feature+3.8 branch of the ZODB from:

Hi Alan
Thanks for the notice. We'll give this a go and report back.
Do you know how exactly it is decided what stays in the cache?

Alan,
I'm replying to the Zope list also, because this issue is perhaps
related to other components there.
I'm running into the same situation: The python process running my Plone
site is steadyly growing.
I'm using Zope2.9.8-final (the one which works with Plone 2.5.5).
What is the plan for Zo
