> TThreadPoolAsyncServer using TFramedTransport silently drops a client service
> using oneway methods when the second message is bigger than the first one.
> I have an application implementing a one way service, depending on it's
> state. I created a TThreadpoolAsync server using the netstd 0.15 version, and
> I noticed that after a point, the notifications stopped coming, but there was
> no error on either side. The methods all worked individually, but some did
> not work after others.
> Eliminating all possible causes on my side, I debugged the source code, and
> discovered that a transport exception was thrown from TEndpointTransport when
> a message size was bigger than the proceeding one, because
> TFramedTransport.ReadFrameAsync was not resetting the message size when it
> was done reading it, thus causing TEndpointTransport.UpdateKnownMessageSize
> to throw the exception. The server interpreted the exception as if the client
> had disconnected, so it silently ignored it.
>
> I've attached a patch that corrects this behaviour
