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.
