When the server is turned off, it cannot accept new connections. It then waits for all outstanding connections to complete. The time the server waits before timing out is configurable in the magnus.conf file, which can be found in server_root/https-server_name/config/. By default it is set to 30 seconds. To change the value, add the following line to magnus.conf:
where seconds represents the number of seconds the server waits before timing out.
The advantages to configuring this value is that the server will wait longer for connections to complete. However, because servers often have connections open from nonresponsive clients, increasing the termination timeout may increase the time it takes for the server to shut down.
