Usage

You can set LISTEN_TIMEOUT to a lower number to guard against faulty connection requests that might indicate a Denial of Service attack.

Depending on the machine capability of holding the threads (in number), you can configure MAX_INCOMPLETE_CONNECTIONS to a higher value and depending on the network traffic, you can set LISTEN_TIMEOUT to a lower value to reduce the chance that an attack can reach the maximum limit.
