Re: [rules-users] Can drools work in multithreaded environment?

I ran into the same issue running JMeter recently. I am getting the same stack trace. I checked my version and I am using 4.0.7 of Drools. Was this resolved by going to 4.0.7 for you? Is there anything else to check? Todd You must update to 4.0.7. You are probably facing the issues we had in 4.0.3.
