A number of active but idle connections can lead to resource attacks. The dimension of time to close connection is defined by a TTUD (TCP-TLS-UDP Dispatcher) TimeOut parameter. To avoid the resource leaks this parameter should be a relatively small value.
First Message time out
TTUD can close a connection if no message is received within a certain time. This time is defined by the parameter First Message time out. The value is 90.
Handshake time out
TTUD has a number of active but idle handshakes, TTUD can close a connection if the handshake is not complete within a certain time. This time is defined by this parameter and the value is 30.
