Unexpected Client Disconnects

[DanielKozimor]

We're running into some odd client disconnects with our appication. It seems
that after a period of time (usually 30-45 minutes - but it varies) FMS will
boot a client for no apparent reason. On server side, application.onDisconnect
gets triggered and, the client gets a "NetConnection.Connect.Closed" event.

It seems like it usually happens to clients that are behind the same router,
but at this point, we're just speculating. The networking stuff in FMS is a
complete blackbox so I'm not even sure what to debug. Anyone experienced this?
Any workarounds? Any logs I can check to figure out why a client would get
booted sometimes?

We do have FMS ping all clients regularly (to figure out latency) and all
clients call a remote method on FMS on a set interval - this was a possible
solution mentioned in some white papers. Clearly, it hasn't helped us.

Here are a couple of things to explore:
-The application logs should provide you more information
logs\_defaultVHost_\YOURAPP\...

-If it is one particular router that is causing the issue it might be network
related.

- Try adding debug traces to your application.

- What version & OS are you running?

It doesn't help. About the only thing I get from the log is that
application.onDisconnect is called but thats just an event listener that gets
called after FMS already decided to kick the client out.

At this moment we're speculating this might have something to do with it -
maybe its random. We noticed this behavior in a few separate instances. We
would have multiple clients connected to FMS and the client that was booted
seems to be one of the ones that was behind a router along with another client.
I don't know if that has anything to do with it. I'm inclined to say its not
simply network related .. 30mins to 1 hour and we're guaranteed a client is
booted.

Windows Server 2003.
