Trunk 5.1.0-snapshot hangs if pounded enough
--------------------------------------------

                 Key: JBRULES-2145
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2145
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core  (expert)
    Affects Versions: 5.1.0.M1
         Environment: quad core, ubuntu 9.04
            Reporter: Geoffrey De Smet
            Assignee: Edson Tirelli
            Priority: Critical
             Fix For: 5.1.0.M1


To reproduce:

svn checkout <drools>
edit drools/drools-solver/pom.xml and comment out the dependencies on 5.0.1
(1) run PatientAdmissionScheduleApp in the working directory drools/drools-solver/drools-solver-examples
Click load testdata01.xml
Click solve

In the output, you 'll see something like this:
Trunk is bugged 35/652
Trunk is bugged 36/652
Trunk is bugged 37/652

At some point it might hang before it reaches 652. It does not happen every time, so try again it does reach 652.
I've seen it occur about 1 out of 3 times.

And if it hangs, it really hangs: all 4 of my CPU's are not buzy etc. Definitely a race condition.
