Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of CICS TG and SNA connected CICS servers.
  ****************************************************************
  PROBLEM SUMMARY:
  After a SNA network error has occurred, CICS TG tries to
  reestablish the connection. If the SNA service provider takes a
  long time to process the ALLOCATE request issued by the Client
  daemon the reported messages are issued. Requests to other,
  unaffected server connections will continue to be processed
  slowly.
  ****************************************************************
  

Problem conclusion

• CICS TG has been changed to close its connection to the CICS
  server when no other sessions to that CICS server exist. This
  prevents the lengthy failed retry attempts.
