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

             Summary: Agent rebalancing is broken
                 Key: CLOUDSTACK-429
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-429
             Project: CloudStack
          Issue Type: Bug
          Components: Hypervisor Controller, Management Server
    Affects Versions: pre-4.0.0
         Environment: KVM, Cloudstack 3.0.2
            Reporter: Roland Kool

After setting agent.lb.enabled to true and restarting my management servers, the agent rebalancing
gets stuck after trying to rebalance the first 16 machines.
The error from the management log is:
