Error description

  • After upgrading from MQ v6 to v7, one thread of a .NET client
    application receives a TCP error code while another thread is
    in the middle of an MQDISC call.  This can cause seemingly
    random failures.  The error logs shows:
    
    AMQ9208: Error on receive from host XXXXXX(1416).
    
    An error occurred receiving data from XXXXXX(1416) over TCP/IP.
    This may be due to a communications failure.
    
    The return code from the TCP/IP (socket.Receive) call was 10058
    (X'274A'). Record these values and tell the systems
    administrator.

    PROBLEM SUMMARY:
    While one thread of the .NET client ends a conversation and
    closes the socket, a thread switch happens and another thread
    attempts to send a heartbeat using the same channel.
