Hi Станислав

You have two relays running at the same IP. Your IP and relays seem
visible to the network:

Port 80 is your DIR port.

If you suffer under potential overload or not enough resources (by what
ever reason) you can reduce.

Run only one relay with OR port only and strict DOS settings. Then wait
a week if everything works. Wait an other week. If still everything is
running well add the DIR port again and wait and wait. Add the second
relay in the same way and finally relax DOS settings.

When ever the relay(s) become unstable go one step back.

This is a recommendation but there might better ways to go.

Good luck!
