Using: 5.2.0.Final of drools camel server , JSON api, and a Stateless Session We are making JSON calls to the camel (execution) server.  Our end-to-end unit tests pass.  Our load tests, however, show that memory is never reclaimed after each call to the rules engine.  After parsing through a heap dump, we see the following path taking up over 800 meg of memory: (kagent) KnowledgeAgentImpl$ChangeSetNotificationDetector The rule base is very small and simple - this is only a problem during a load test (or over the course of a weeks worth of calls).  We make the following call 10K times: {   "batch-execution": {     "lookup": "ksession1",     "commands": [       {         "insert": {           "out-identifier": "tc_1",           "object": {.....}           }}]}} The knowledge-services.xml configures :  - kagent id="agent1" kbase="kbase1" new-instance="true"  - ksession id="ksession1" type="stateless" kbase="kbase1" node="node1"  The rules just update the inserted "timecard" fact. Because I'm using a stateless session, I don't think I need to dispose of the agent...and I don't think there is a way to call dispose using the json/Execution Command api. We are calling the camel (execution) server from a non-java environment to process employee timecards entries and evaluate for overtime calculations. Thanks! Mike
