This setting adjusts or disables the inactivity timeout on connections to the server. The inactivity timeout is used to abort long-running requests.

The value specified is passed to the Node.js server.setTimeout() method.

• 0 - Disables the inactivity timeout;

• Integer > 0 - Sets the inactivity timeout, in milliseconds.

The default value, if the setting is not specified, is 3600000 (1 hour).

As of Profound.js version 7.31.0, if socketInactivityTimeout is not explicitly set, it automatically aligns with the timeout setting, converted from seconds to milliseconds.

For example:

• If timeout is set to 7200, then socketInactivityTimeout defaults to 7200000 (2 hours);

• If neither setting is specified, the default remains 3600000 (1 hour).

In previous versions, socketInactivityTimeout always defaulted to 3600000 regardless of the timeout setting. This could cause premature socket termination in proxy mode when timeout exceeded one hour. With auto-alignment, socket-level timeouts now match the session timeout automatically, preventing these premature disconnections.
