Hi Nirmal, For some reason, that method is not getting called. I've pasted my stacktrace again with the drools methods removed:
--- Daemon Thread [Thread-56] (Suspended (breakpoint at line 137 in CloudControllerClient)) owns: CloudControllerClient (id=2433) owns: DefaultAgenda (id=2434) CloudControllerClient.spawnAnInstance(Partition, String, String, String) line: 137 RuleTasksDelegator.delegateSpawn(PartitionContext, String, String) line: 92 // // drools methods hidden // AutoscalerRuleEvaluator.evaluateMinCheck(StatefulKnowledgeSession, FactHandle, Object) line: 86 ClusterMonitor.monitor() line: 99 ClusterMonitor.run() line: 72 Thread.run() line: 744 --- Would you expect to see AutoscaleAlgorithm.getNextScaleUpPartition executed somewhere in the stack of calls?
