      Description

      Troubleshooting an adapter that does not seem to run correctly.
      Left system running over night.
      Discovered an oom log line within the adapter logs box in the GUI:

      2015-07-23 04:55:18,675 - INFO [worker-ETLWorker-0-EventThread:o.a.t.i.z.DefaultZKClientService$ServiceDelegate@447] - ZooKeeper session expired: localhost:2181
      2015-07-23 04:55:19,440 - ERROR [worker-ETLWorker-0-EventThread:o.a.z.ClientCnxn$EventThread@521] - Error while calling watcher
      java.lang.OutOfMemoryError: PermGen space

      The server is responsive, as is the cli. Zookeeper and kafka are both still running (this is a kafka 2 webLogs stream adapter being debugged)
