[jira] [Created] (SOLR-16046) Thread leak in TestLeaderElectionZkExpiry

Houston Putman created SOLR-16046:
-------------------------------------

             Summary: Thread leak in TestLeaderElectionZkExpiry
                 Key: SOLR-16046
                 URL: https://issues.apache.org/jira/browse/SOLR-16046
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Houston Putman


Currently the {{TestLeaderElectionZkExpiry.testLeaderElectionWithZkExpiry}} test fails roughly 11% of the time due to zombie threads.

These are {{zkConnectionManagerCallback}} threads used by the SolrZkClient.

In {{ConnectionManager.process()}}, the method being called by the thread, it is currently swallowing up an interrupted exception and always looping until a valid connection can be made to zookeeper.
