Request Refused and sync error

The issue is not serious and it shouldn't be signaled by a stack trace. We will fix that.
It is caused by a rare race condition, in which a session is closed while it is being recalled by a rebind request. It is a special case of the condition that leads to the "Sync error".
The only problem is that the client, upon the closing of the session, may not be able to recover by opening a new session automatically.

"The only problem is that the client, upon the closing of the session, may not be able to recover by opening a new session automatically."

So, does this mean, the client has to close and open the application again? I mean, what is the impact of this on an application. The app is basically pushing quote data to front end.

Thanks,

Thinking again to the race condition that can cause a session to be closed while it is being recalled by a rebind request,
there should be no case in which this can lead to an incorrect behaviour on the Web Client Library:
the closed session should always be obsolete, thus not needing to be recovered.

Please provide us with a longer Server log snippet, containing the above stack trace, so that we can ensure that this is the case.

That was the full stacktrace I got.
Well, today i did not get any errors, so, will repost when I get the error again.

If you have got only the stack trace,
then you probably have a log configuration too restrictive.
We would need some log produced by the "LightstreamerLogger.requests" logger at INFO level.
