Drools OOM when loading session ------------------------------- Key: DROOLS-1014 URL: https://issues.jboss.org/browse/DROOLS-1014 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.3.0.Final Environment: Mac OS 10.10.5, Eclipse Mars Release, Java 1.8, Drools 6.3.0.Final Reporter: Artur Kronenberg Assignee: Mario Fusco Priority: Critical Attachments: test-standalone.zip I ran into an issue loading the session from my JPA. I am getting this stacktrace: http://pastebin.com/PMKpdBWM This is happening for this rule: http://pastebin.com/HZmLmsEH And this module: http://pastebin.com/2Q6k73tC What I am doing is: 1. Create a new session 2. Insert an ApplicationEvent 3. fireAllRules 4. Reload -> OOM The ApplicationEvent has a list of 6345 facts in there. I load them from a CSV file, and use drools to insert them into my knowledge base as facts. When I restart my server and have the session reloaded, it ooms when trying to deserialize the session. I am still looking for a workaround. I am not sure what is happening and could not find any more info at this point. I am using: JPA + Hibernate 4.2.21.Final org.codehaus.btm:btm:2.1.4 as a standalone JTA platform Let me know if there's any other info needed. Thanks, Artur
