      Description

      Use the attached repeat.sh to run ObserverTest repeatedly by doing:

      src/repeat.sh ObserverTest

      The test will will fail eventually after a few iterations; should be only a few minutes.

      The line that fails in the test is:

      zk = new ZooKeeper("127.0.0.1:" + CLIENT_PORT_OBS,
      ClientBase.CONNECTION_TIMEOUT, this);

      Attached as out.txt is the output showing a successful run, for comparison, followed by a failed run.

      Note that in the seconds before the test fails, in the following lines, that there is a 24 second gap in time (between 22:13:02 and 22:13:26):
