Hello, Our Guvnor 5.3.0 is generating an OOM and crashing the server. At the time of the crash we could see lots objects holding a lot of stuff in memory, most notably 23,878,166 org.drools.reteoo.JoinNodeLeftTuple, each of which takes 72 bytes. For 1.7 GB of heap. I believe the real issue is something is going wrong in guvnor that it is creating way to many of these org.drools.reteoo.JoinNodeLeftTuple objects. Do you guys have had this issue? Is this because of a Guvnor guided editor bug?
