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

             Summary: Supervisor keeps restarting forever
                 Key: STORM-1915
                 URL: https://issues.apache.org/jira/browse/STORM-1915
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-core
    Affects Versions: 1.0.1
         Environment: Linode 4GB running on KVM - Ubuntu 14.04 LTS
            Reporter: Gergely Nagy


While submitting a topology with to a 20 node 40 worker strong cluster, the supervisor keeps throwing errors and keeps restarting the workers it is supervising.

For this reason the topology never starts, instead it keeps dancing by reassigning the bolts and spouts forever.

I'd love to attach the logs here but I can't find any upload button in the JIRA form.

The error basically says:
