Vitaly Lomov created DROOLS-498: ----------------------------------- Summary: Memory leak in stateful session after retracting facts Key: DROOLS-498 URL: https://issues.jboss.org/browse/DROOLS-498 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 6.0.1.Final Reporter: Vitaly Lomov Assignee: Mark Proctor Priority: Minor After adding many simple facts into the stateful session and then removing them, the factHandles for the removed facts are still referenced by the session. Eventually getting "java.lang.OutOfMemoryError: GC overhead limit exceeded" with the stack trace (sometimes) similar to DROOLS-411. Someone on StackOverflow suggested iterating through whatever factHandles remain after deletion and delete those, but I get no factHandles (correct, since I removed all facts). See screenshot for objects in memory _after_ deleting all facts. -- This message was sent by Atlassian JIRA (v6.2.3#6260)
