There are six network failure detection parameters that can be configured in the EMS server.
server_timeout_client_connection
server_timeout_client_connection limit
In a server-to-client connection, if the server does not receive a heartbeat for a period exceeding this limit (in seconds), it closes the connection.
client_timeout_server_connection
client_timeout_server_connection limit
In a server-to-client connection, if a client does not receive a heartbeat for a period exceeding this limit (in seconds), it closes the connection.
server_heartbeat_server
server_timeout_server_connection
In a server-to-server connection, if this server does not receive a heartbeat for a period exceeding this limit (in seconds), it closes the connection. This parameter applies to connections from other routes and to the backup server connection.
We recommend setting this value to approximately 3.5 times the heartbeat interval of the other server. When the other server or the network are heavily loaded, or when client programs send very large messages, we recommend a larger multiple. That is the 3.5 multiplier is a minimum that we recommend. That is 3.5 times should be the minimum setting. We can not tell the exact recommendation. You may have arrived at your values through experimentation.
Be careful reducing the multiplier because a lower value may cause false disconnects.
