Very High Memory Usage and frequent restarts with OH4

I realized too when upgrading to OH4.0.1 that the container is constantly restarting (thanks to iCloud reporting connection by email).
I then stepped back to OH3.4.4 unfortunately the same constant restarting is now on 3.4.4 too.
I am pretty sure this was not happening before
For my container of different OH versions, I have different mount points on my host system.
Prior to upgrading I always stop the running old version container copy the data to the new version location and start the new version OH container.
Therefore there is for sure no side effect that I have started OH4.0.1.
Though one thing that I did before starting the OH4.0.1 container is that upgraded the host system to the newest version by apt-get update/upgrade.
I at last started also my oldest version which I ran for about half a year 3.4.2 and had the same effect: running for a while and then dropping dead without any notice in the log.

Any idea how to get more information and debug? I am a little desperate.
