CSS Packet Capture

[ejaro]

Is it normal for a CSS to close it's health check by sending a a RST flag? As have not captured or seen any packets set with FIN. All the packets or requests are completed well under the set time.

Ejaro,

Please see the following:

By default and in compliance with RFC 1122, the CSS sends a reset (RST) to close the socket on a server port for TCP keepalives
