AltostratusRound-robin method not load balanced
NacreousThis is often a common misunderstanding of how round robin works in F5.
It's TMM handle the round robin independently
So if for example you have 4 TMMs, first 4 requests might most probably forwarded to server1, one request from each TMM.
Try disabling server1 and check if traffic is forwarded to server2. Or simulate a lot of requests and check statistics.
ping-tI disabled server1, but could not communicate to server2, and I got a connection error on the source server sending to VIP.

So you have bigger problem than load balancing. You said that monitor is up, what kind of monitor are you using?
Can you try a curl also in server2 from F5? Does it work?
- ping-t
It defines a monitor for the SMTP protocol, which periodically connects to the SMTP server and sends EHLO commands and other commands to check for responses.

Seems to me like server2 isn't configured correctly to receive the traffic. You can run a tcpdump to see what's happening with the traffic that's being sent to it. I'm in agreement with Injeyan_Kostas that we would need to know what the health monitor is because the server could be passing a basic healthcheck that verifies a port is listening but nothing at an application level that would mean the server is responding with content.
