NonClusterManager does not prevent concurrent execution of jobs

    XMLWordPrintable

Details

    Description

      The implementation of ClusterManager for non clustered licenses does not implement any kind of locking at all.

      This means oncePerCluster (such as the ClusterSafetyJob) jobs can run concurrently, amongst other problems, which can lead to errors.

      Update: see the comment below for patch instructions.
