Shutdown configuration
The configuration items on this page allow you to configure Liberator’s behaviour on shutdown.
sigterm-shutdown-options
This configuration item changes the behaviour of Liberator when it receives a SIGTERM signal. The standard behaviour is for Liberator to initiate an immediate shutdown. When sigterm-shutdown-options is set, Liberator initiates a graceful (delayed) shutdown.
You can send the SIGTERM signal to Liberator using the Bash built-in command kill or Linux’s /bin/kill command.

During a graceful shutdown, existing connections are still honoured, but no new client connections are accepted. Liberator will shutdown automatically either when all clients have disconnected, or at the conclusion of the grace period; whichever happens first.
You can also initiate a graceful shutdown by sending Liberator the UDP command shutdown, or by executing the monitoring operation "shutdown" under the rttpd.server.liberator MBean in the Caplin Management Console.
StreamLink clients can subscribe to Liberator’s /SYSTEM/NOTIFY/STATE subject to be notified when a graceful shutdown has been initiated. For more information, see Liberator system subjects.
