Hello,

to prevent the CSS from sending traffic to a death server, keepalives should be used.

Looking at your config, you are using ICMP to check the health of your server. This means that you are only checking the network layer.

In your case, the server keeps responding to ICMP requests, but the upper application has failed.

Which application is this? Is it a webserver?

If it is HTTP, you can for example check an URL to see if the webserver is still alive.

A possibility for you is the make a TCP connection to port 9800.

keepalive type tcp

keepalive port 9800

But all depends on your application. If the TCP port keeps responding but the application failed, this will not work either.

Can you give a description of the application you are running?

Hope this helps.

Kind regards,

Dario
