InMemorySessionFactory has apparent memory leak ----------------------------------------------- Key: DROOLS-1364 URL: https://issues.jboss.org/browse/DROOLS-1364 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.5.0.Final Reporter: Eli Israel Assignee: Maciej Swiderski I'm running drools with a runtime manager creating using PerRequest strategy and SessionCache turned on. (I process a LOT of requests but I want each one to be isolated) The SessionCache properly gets rid of sessions that have hung around too long, which is great. But the InMemorySessionFactory keeps a copy of every session it ever created, which -- it seems to me -- impedes garbage collection of unneeded, old sessions. It's possible I'm just reading this wrong, but examinations of running code using VisualVM show a LOT of RightTuple objects hanging around, attached to sessions and their GC root appears to be the InMemorySessionFactory.
