I created a "reproducer" here[2]. Be aware that this is failing nondeterministically, so with high probability it is a nasty race condition. I tried to debug this a bit and this is the output of some variables that is available on this line [3]: Returned fire count: 0 Head: null Group: AgendaGroup 'MAIN' Group is auto deactivate: true Limit reached: false IsInternalFire: false IsFiring: true [1] http://pastebin.com/sjLjQwgX [2] https://github.com/kiegroup/kie-benchmarks/pull/8/files [3] https://github.com/kiegroup/drools/blob/3038a1b9287978069bcb2765dc684f696...
