 - Two new server parameters related to ping checking were added:
 
-1. ping-cltt-secs which allows the user to specify the number of seconds that must

-2. ping-timeout-ms which allows the user to specify the amount of time the server
-   waits for a ping-check response in milliseconds rather than in seconds.
