  ****************************************************************
  During startup of a svrconn channel with sharecnv>0,
  rriAcceptSess detected an error, and channel startup failed.
  When freeing control blocks associated with the terminating
  channel, with the PTF for PI05308 applied a call is made to
  cciEndConv to free the conversation control block, however an
  error in the parameters passed on the call prevent the expected
  conversation block being found. This is unexpected, and CSQXFFST
  is called to produce an FFST.
  The FFST incorrectly indicates it was produced by rrmSubSpecial1
  rather than cciRemoveConv.
  

Problem conclusion

• The parameters passed to cciEndConv have been corrected,
  preventing the FFST being issued. FFSTs issued by cciRemoveConv
  have also been changed to correctly indicate this routine as the
  origin of the FFST.
