  ****************************************************************
  When a SVR-RQSTR channel pair is stopped by the network or by
  RQSTR channel the SVR channel goes in STOPPED state preventing
  the channel to be started again by the RQSTR. The channel has
  to be manually started in the SVR side.
  
  This problem affects SVR channels that do not have a CONNAME
  defined and zero short/long retry counts.
  

Problem conclusion

• rriWriteCompMsg in CSQXRMSS has been changed to avoid disabling
  server channels configured with zero retry counts allowing the
  channel to change to INACTIVE state.
