Raphael, the option to disable jitting is in the class PermGenThresholdOption and the property name is drools.permgenThreshold.
The idea there was that the main problem that jitting could cause is the PermGen occupation, so we decided to provide an option to set the percentage of PermGen space that can be used before it stops jitting. Of course if you set that value to 0 it will cause to disable jitting completely. As for the problem you're reporting it sounds a bit weird to me because we're using a cached thread pool Executor there. Anyway I'll try to reproduce the problem and check how I could prevent this. Thank you for having reported it, Mario -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Out-of-Mem-and-thousand-threads-Disabling-JIT-tp4026694p4026744.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
