> 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.
