We are developing a MIDlet using a SocketConnection.
If this Connection runs over the WirelessLAN Adapter ( Nokia N93 ), everything works fine.
If we start the Connection over UMTS, we have the following error-message:

java.io.IOException: SymbianOS error = -34 : Allgemeiner Systemfehler

So what´s wrong, we don´t know what to do. Please help.
