Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of WebSphere MQ Version 7 Release  *
  *                 1 Modification 0.                            *
  ****************************************************************
  * PROBLEM DESCRIPTION: If a conversation is initiated with a   *
  *                      client and the TCP/IP write fails in a  *
  *                      SVRCONN channel with a SHARECNV         *
  *                      attribute greater than zero, the        *
  *                      CHINIT does not completely clear the    *
  *                      conversation.                           *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the client connects to the CHINIT a conversation block is
  created.  If a TCP/IP write fails in early processing for a
  SVRCONN channel with a SHARECNV attribute greater than zero the
  conversation blocks may not be completely cleaned up, leaving
  a control block and the pointers to it.
  

Problem conclusion

• The code was changed so that in a SVRCONN channel with the
  SHARECNV attribute greater than zero the conversation is
  properly cleaned in the event of a TCP/IP error.
