Description

I encountered a problem when testing the modbus server. The server exits when the client disconnects. I used the demo from https://github.com/stephane/libmodbus/blob/master/tests/bandwidth-server-many-up.c. The server hangs on line 128 (close(master_socket);).

Expected behavior or suggestion
