[ https://issues.jboss.org/browse/DROOLS-2825?page=com.atlassian.jira.plugi... ] Mario Fusco resolved DROOLS-2825. --------------------------------- Resolution: Explained In your reproducer you're not running drools in STREAM mode. In fact you correctly set the STREAM mode in the kieBaseModel, but then you totally override that configuration by doing: {code:java} KieBaseConfiguration configBase = ks.newKieBaseConfiguration(); configBase.setProperty("drools.propertySpecific", "ALWAYS"); kbase = kcontainer.newKieBase(kieBaseName, configBase); {code} By doing so you are creating a kiebase with a new configuration and then the existing one defined in the kmodule is ignored. Also note that the other property that you're setting it's useless because it is the default behaviour in drools 7. If you add {code:java} configBase.setProperty("drools.eventProcessingMode", "stream"); {code} to the new config, or if you simply obtain the kbase with the config defined in the kmodule (something that I suggest) with {code:java} kbase = kcontainer.getKieBase(); {code} then drools will run in stream mode and the expired events will be correctly evicted from the working memory as per your expectation. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
