I upgraded to Openhab 2 from Openhab 1.8.3 recently from Openhab 2.4 on Windows 10 and have issues using the legacy knx binding. I have a large knx installation (several hundred group addresses) and have been using Openhab and knx successfully for many years. Openhab 2.4 (or Openhab 2.5M4) work fine for several hours, sometimes a day or two. Then suddenly the bus gets floated with seemingly random telegrams (10 per second whereas I normally have one per second); often the same telegrams. I then have random behavior with bus elements switching on and off (my house then turns into a crazy mess and so does my wife).
Any hint what could be going on? I only have this issue with Openhab 2. Openhab 1 runs normally.
