Hi. I've been playing around with the new "cache-size-bytes" setting to limit the ZODB cache sizes.
My ZODB 3.9.3 (Zope 2.12 / Plone) config had a setting of cache-size-bytes to 128mb and a cache-size of one million (to effectively disable the object number based checks). This was without ZEO, a simple FileStorage with a blobstorage enabled. When using and testing this for a while in a setup with two database connection threads, things worked fine for a while, but after 10 to 15 minutes of various load patterns things broke down. Both connections started to minimize their connection cache down to zero objects continuously. It looks like the active cache size isn't properly reduced at some point and as a result the cache thinks it is already using the maximum amount. Has anyone used the bytes limited cache in production yet and has any experience with it? I can try to isolate the problem some more. Playing around I did everything from loading objects, packing the database, minimizing caches, so it's hard to know what might cause this. Thanks, Hanno _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
