This seems to proof my theory, to be a UDP best-effort communication issue . > - starting the event tester in a second osgi framework on the same host (no > network connection in between) gives me the same behavior as on running over > a network cable. So some events still missing then.

I'll bet for the best-effort communication, because the test that you performed on a single OSGi environment proved that the event are sent by the UPnP Device, so the problem seems to be the receiver over the network. If you want to perform more test you should sniffer the packet sent on the network by means of Wireshark and check that the importing host receive all the UDP with all the event of all the device exported by the remote host.
