Re: [rules-users] Problem when I cleaning the production memory.

Finally I resolve my issues destroing the Knowledge Base and then re-create it when the problem occurs. I confirm that version 5.6 is more stable than 5.5. In 5.6 i don't have the non-deterministic behaviour anymore whereby it's impossible to remove a knowledge package. In 5.6, however, the same issue is still present when i add a knowledge package in the knowledge base that generate a nullpointerexception when matching with facts already present inside the session. In 5.6 the issue can be accurately examined because have a deterministic occurrences! The problem seems to be: * KnowledgeBase fail to add the new package due to NullPointerException. * When the cleaning is called KnowledgeBase want remove the package that previously it couldn't add. Probably I have had a lot of problems because I'm not doing things in the right way. I hope this experience can help someone. -- View this message in context: http://drools.46999.n3.nabble.com/Problem-when-I-cleaning-the-production-...
