Hello Terry,

 but in your modbus_handler() thread function do 
you actually break out of the while(TRUE) loop and call netconn_close() 
and netconn_delete() when the remote client disconnects ?

I can show you more. I think I am handling what you say. But I'm not sure.

I'm no expert on Lwip, but looks ok to me. Might be worth adding a printf or whatever method you have to debug to check that the connection is actually being closed. Not sure if you need a netconn_close() as well as netconn_delete() or not.

I don't think you want:

    newconn = NULL;
 }
 else netconn_delete(newconn);

in the listen thread.
