Mario Fusco commented on DROOLS-1059:
-------------------------------------

Please provide a reproducer containing a few rules similar to yours plus a test method with an usage pattern as close as possible to how you're using the KieBase and KieSessions in production. Even if this won't reproduce that exception at least it will give me some hints on what you're doing and a point from where to start my investigation.

> 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 unable to find a query (not always the same one).
> I got this error for 0,6% of my requests.
> *+Following the stack trace : +*
> Unable to find query 'checkAndBindBasket'
