    * PROBLEM DESCRIPTION: The DISCINT attribute does not have an  *
    *                      effect on SVRCONN channels defined with *
    *                      SHARECNV > 0.                           *

    * RECOMMENDATION:                                              *
    ****************************************************************
    The DISCINT attribute of channels defines the amount of time
    that can elapse between useful work on a channel before the
    channel will timeout. A error in calculating the timeout used
    for receiving from the socket, results in the DISCINT value not
    being upheld. This results in the channel not timing out in this
    scenario based on the defined value.
    

Problem conclusion

  • The code has been updated to ensure DISCINT has an affect on
    SVRCONN channels with SHARECNV > 0, resulting in the channel
    timing out when applicable based on this value.
