Hi, I'm running zope232src on Linux. My Data.fs packed has a size near 250 MB. My zope server takes 70Mb of RAM when started, ending after a week taking 1GB of RAM, and eventually restarts automatically (z2.py -Z). When it is at 1GB of RAM there is on top of refcounts in Control_Panel/DebugInfo the class BTrees.IIBTree.IIBTree with something like 3500 refcounts. Then there is OFS.Image.Image with 1000 refcounts and other classes with refcounts below this. I have a lot os catalogs in my Data.fs some with 10,000 others with 5,000 objects indexed. I've not converted all of my zcatalogs to the new Btree implementation with manage_convertBtrees. But now I'm thinking of doing that since I think the memory leak is in Btrees. I also have a BtreeFolder from the product BtreeFolder with 15000 folders created in it, but I dont think it could be from here. I'm doing debug to find this memory leak. Any hints if this memory leak could really be related with Btrees?
