# Client Heartbeat Server

In a server-to-client connection, clients send heartbeats to the server at this interval (in seconds).

The Client Heartbeat Server property must be specified when a Server Timeout Client Connection is set. The Client Heartbeat Server interval should be no greater than one third of the Server Timeout Client Connection limit.

This property also ensures that garbage collection occurs on the connection. Collection is triggered by incoming messages and heartbeats. If the size of messages can vary widely or there is not a steady stream of message traffic, you can use this property to ensure that collection occurs.

When omitted or zero, Client Heartbeat Server is disabled.

## Classic Configuration

The client heartbeat server interval is set using the client_heartbeat_server property in the tibemsd.conf file:

    client_heartbeat_server = interval

## Administration

This property cannot be set using the administration tool.
