  *                      incorrectly configured IPIC connection  *
  *                      do not complete.                        *

  ****************************************************************
  Worker threads allocated to ECI requests remain allocated if an
  IPIC connection cannot be established. The client application
  does not receive a response.
  If all the worker threads are allocated, subsequent attempts to
  send ECI requests to the Gateway daemon result in error rc=61445
  ERROR_WORK_WAS_REFUSED being returned to the client application.
  
  If the maximum number of active connection manager threads is
  reached before the maximum number of worker threads, the
  following message is returned to the client application:
  java.io.IOException: CTG6668E Initial handshake flow failed:
   ERROR_CONNNECTION_FAILED
  
  The Gateway daemon does not shut down normally.
  

Problem conclusion

• CICS TG has been corrected. The failure to establish an IPIC
  connection does not deadlock worker threads.
