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

             Summary: infinispan exception during wildfly app server startup
                 Key: ISPN-7164
                 URL: https://issues.jboss.org/browse/ISPN-7164
             Project: Infinispan
          Issue Type: Bug
         Environment: RHEL 7, VMWare ESX 5.5, 
Wildfly 8.2.1 cluster with 6 nodes
            Reporter: Purush Reddy


We are seeing the following exception in the cluster node startup. Please note that this issue is sporadic.
This seems like race condition. the application on one node is calling evictAll() before the other node (throwing the exception) fully starts up and initializes the region.
