High Connections on Exchange iApp Virtual Server

We are using exchange 2016 iApp have configured 2 Virtual Server on the same LTM.

 

OWA Clients > VS 1(iRule to forward traffic to VS2) > VS 2 > Exchange servers.

 

Analytics > Virtual Server > Traffic Details > Connections shows that VS 2 has unusually high amount of connections. When I do tmsh show sys connections cs-server-addr VS2-VIP, I see nothing When I do tmsh show sys connections cs-server-addr VS1-VIP, I see normal connections. But they show that ss-client-addr and ss-server-addr are VS2 self IP and exchange server addresses.

 

How can I see what these connections are? Am I missing something?
