Okay, I try it. Im still confused about it, because the server write every second these 40 Lines of Error, all I can see out of that is that something is with a Chunk. Anyways thank you for your fast reply.
Well, the problem is the server does not crash when this happen. It stays online but no one can connect on it. The last crash report is from January, what i can attach ist the complete Log of today. The problem that I reported started in Log3 Line 738
To answer @Skaijie's question,
We've been "living" with the 7-8 minutes pause on the white loading screen since the workaround of the red mojang screen hang.
It's not ideal, but at least the game runs normally after the aforementioned wait period.
We're on a normal PS4, we have the disk version and we're up-to-date (1.16.221)
So yes, it's still an issue.
