Yes, the Agent is also 4.1

I think you mean at the agent?

But what I think is weird is that the mgmt server directly closes the 
telnet connection as well and nothing shows up in the logs.

In the mgmt server log I found this:

2013-04-02 22:08:41,156 INFO  [utils.nio.NioServer] 
(AgentManager-Selector:null) NioConnection started and listening on 
0.0.0.0/0.0.0.0:8250

What I did notice is that when I shutdown the mgmt server the Agent 
connects for a second:

2013-04-02 22:07:53,689 INFO  [utils.nio.NioClient] 
(Agent-Selector:null) Connecting to 31.25.X.X:8250
2013-04-02 22:07:53,934 INFO  [utils.nio.NioClient] 
(Agent-Selector:null) SSL: Handshake done

And then the mgmt server exists and the connection gets lost.

ANY clues about this weird behavior?
