Countermeasure: The user server might have issued a synchronous-message transfer function (such as dc_mcf_sendrecv), and protocol might be waiting for a message from a remote system. Check the user server status and remote system status. Also, if using TP1/NET/TCP/IP, you can execute the mcftlscn operation command to check the status of each connection in the execution results (ddddd: detail status).
