Mysterious TCP Peers

[Deleted User]

I'm running latest client and server code. And have the following to ensure I am only using UDP:

Client:

this.peer = new LitePeer(this, ConnectionProtocol.Udp);

Server:
PhotonServer.config (commented out TCP listener)

<!--
		<TCPListeners>
			<TCPListener
				IPAddress="0.0.0.0"
				Port="4530"
				DisableNagle="true"
				InactivityTimeout="5000">
			</TCPListener>
		</TCPListeners>
		-->

So on the client I am only using UDP, and on the server I have TCP completely disabled.

In the server logs, I see it adding a UDP listener & TCP Policy listener. All normal so far...

But when I check out PhotonDashboard or the PerfmonCounters I see the TCP peers count climbing continually. It never goes down it only increases. Eventually it reaches a couple hundred and I restart the server to clear them out.

This has started happening since I updated to Unity3. Any ideas?

It sounds like the policy connections do either never disconnect - or it's a bug and the tcp peer counter is just not decremented. We will check this asap.

Did you notice if these ghost peers count towards the license limit?

I am not sure if it contributes to the license limit. We keep restarting it when they get too high.

Interestingly I just noticed that sometimes TCP CLR Commands goes up to 1 per sec for just 1 second, then back to nothing. Very rare, but it happens. Attached a screenshot.

The policy connections to port 843 are TCP. The clr returns the policy file, so that is fine.
This happens every time a new web player client connects. Otherwise the web player wouldn't be able to communicate with photon at all.

Just confirmed that the TCP peers to count towards the licence limit. Just had to restart the server.

On our test server, we have the same effect but didn't notice it. I can't reproduce this locally, yet.
It seems to be happening only under certain conditions or rarely. How often do the TCP user count increase in your case?

For the time being, I could supply you with a temporary unlimited license, so no users are rejected because of the CCU limit until we find and fix this.
