> An Event inserted into the stateful session is correctly processed, but starts near-100% CPU load. Logic implemented according to drools-compiler/src/test/java/org/drools/integrationtests/CepEspTest.java, but needs longer observation to notice CPU load. No rules necessary to demonstrate this.
> I'm going to attach maven project that demonstrates the problem within the test method testEventBasedCPULoad (please, ignore other two test methods - related to different bug). 
> Profiling of the running session shows org.drools.common.AbstractWorkingMemory.executeQueuedActions() as the cause of the problem.
