[rules-users] limits on number of rules in Guvnor in a package, loaded in knowledge base

[Michael Anstis]

IIRC there was a bug in Drools Expert 5.3 that was not releasing event
listeners correctly that led to a memory leak - it might be related to what
you have experienced. IIRC this was fixed for 5.4.

Are you able to try with Drools suite 5.4.0.beta2?
