hi,
i have a problem in my adapter that it is initialized then make a subscribe to items from another adapter to do some calculations an then push the result to lightstreamer.
sometimes after few minutes a some connection exceptions is appeared from the connection listener as :

public void OnActivityWarning(bool warningOn)
warningOn = true

public void OnFailure(PushServerException e)
e.Message = No data from server

what does these exceptions mean? and what the reasons which make that ?
