    AMQ9271E: Channel 'YMT.SV.SRVCON' timed out.
     
    EXPLANATION:
    A timeout occurred with error code 0 (X'0') while waiting to receive from the
    other end of channel 'YMT.SV.SRVCON'. The address of the remote end of the
    connection was '10.XXX.XX.XXX'. The timeout value used was: 65 seconds.
     
    This error is an indication that the other end of the channel has become
    unresponsive or has terminated without the usual TCP/IP closure packets. The
    problem could be an abend of the remote channel MCA or a hang in a remote
    channel exit. The problem could also be that a router's or firewall's idle
    timeout policy has cut the connection such that a receive only ends when it
    eventually times out (as the TCP connection may not necessarily have been
    closed in a graceful manner). Normally a channel heartbeat keeps a connection
    alive, but if a router's or firewall's idle timeout is less than the channel
    heartbeat interval then that is a likely cause for this error. But if no
    channel heartbeat is configured then if a router's or firewall's idle timeout
    is less than the channel's disconnect interval, or if no channel disconnect
    interval is configured, then that can also be the cause for this error.
    ACTION:
    Check the other end of the channel for any errors that might point to being the
    cause of the timeout. If a router or firewall is present then check that any
    configured timeouts are not less than the channel's HBINT and/or DISCINT
    attribute values.
