    How Executor Service works in Cluster Environment-JBPM6

    Manjeet Singh Newbie

      I tried to use Executor service in cluster environment.

      But sees error in multiple node

      Caused by: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.drools.persistence.info.SessionInfo#3857]

      In my Sample Process I have 10 service tasks and 4 nodes in Cluster environment.

      In every few minutes I am getting this irritating exception.

      Is there a way to make sure only one instance run in one node.

      If any node goes down it will automatically fail over to another one node in cluster.
