Startup sequence for Homematic Binding?

I am running Homematic (ff. HM) on a CCU3 with firmware 3.41.11 and OH2 2.4 on Raspbian Stretch. HM is connected to OH2 by the Homematic Binding.

I’ve experienced several times, that it seems to be crucial, that OH2 is down when the HM system ist starting up. If OH2 is running while restarting HM, the HM system locks in a load-loop and no HM program runs. So I have to shutdown OH2, then restart HM and start OH2 again.

That leads me to the question, whether this behavior is intended or not. If not, I’d appreciated ideas on what could going wrong.
