[rules-users] Starting engine using fireUntilHalt and inserting no facts results in 50% CPU usage

[Tina Vießmann]

Hi,

I'm experimenting with asimple Fusion application. I'm using 
fireUntilHalt() to start the engine.
When I start my application it uses nearly 50% of my CPU without any 
facts being insert. This remains while my application is idle. Why is that??

My machine has a 2Duo T9300 with 2,5GHz an JDK6u21.

Thanks for your help. :)
