             Summary: Drools can't find rules under stress
                 Key: DROOLS-1059
                 URL: https://issues.jboss.org/browse/DROOLS-1059
             Project: Drools
          Issue Type: Bug
          Components: core engine
    Affects Versions: 6.3.0.Final
            Reporter: Massinissa BOUZIAD
            Assignee: Mario Fusco
            Priority: Blocker


In my knowledge base, I have many rules. 
All of them are working very well in production with drools 6.0.1-FINAL even in stress condition hight trafic (arount 40 hits seconds)

This bug append when we made an upgrade with drools 6.3.0-FINAL which is compatible with jdk8 mandatory in my case.

So now when I put my rules under stress test (benchmarking) I got this random error.
Drools is unale to find a query (not always the same one).
I got this error for 0,6% of my requests.
