DataIn fires once, and then does not seem to fire anymore (IPPort/ICMPPort/UDPPort/MCast)

Please keep in mind that the DataIn event is not reentrant: you must exit from it as soon as possible to enable firing the next DataIn Event. The rules on how the events are fired are explained in the help files: the EOL and MaxLineLength properties may apply.
