    Hello Siva!

    Do you happen to know the source IP of all those connections?

    I would start by looking at the connection table during that spike. Something like this...

    tmsh show sys connection cs-server-addr <VIP> cs-server-port 8080

    If everything comes from the same IP it could possibly narrow your tshoot down to a specific client.

    Best of luck!
