-----------------------------------

             Summary: Concurrent access timeout on StatefulBean when invoked via StatelessBean
                 Key: WFLY-9492
                 URL: https://issues.jboss.org/browse/WFLY-9492
             Project: WildFly
          Issue Type: Bug
          Components: EJB
    Affects Versions: 10.1.0.Final
            Reporter: Thies Rubarth
         Attachments: sfsbLock.zip

We are having issues with a stateful bean that is invoked serveral times in a request to calculate things. We have a StatelessBean, that is called via REST and calls another StatelessBean which calls the StatefulBean which is request scoped. When we have parallel requests it comes to ConcurrentAccessTimeoutExceptions on the StatefulBean, although we shoudn't have concurrent access since the Bean is request scoped.

This is the stacktrace we get:

Caused by: javax.ejb.ConcurrentAccessTimeoutException: WFLYEJB0228: EJB 3.1 FR 4.3.14.1 concurrent access timeout on StatefulBean - could not obtain lock within 5000 MILLISECONDS
