CirrostratusTCP Profile > Zero Window Timeout
Another one for you all. The TCP Profile Zero Window Timeout setting description states "If the Zero Window Timeout timer elapses, the BIG-IP system terminates the connection."

Once the F5 receives the tcp zero window, F5 starts the counter. The default zero windows timeout is 20 secs (20000 ms).
F5 will send TCP KeepAlive segments to checking whether the tcp state has been changed.
If F5 keep receiving ACKs with ZeroWindow for the TCP KeepAlives, The F5 counter won't be reset.
Once it reaches the ZeroWindow timeout, F5 will send TCP RST to client side and server side, and clear the connection entry.
