World gen error

[Livux]

Ummm, my server was overloaded at world generation with this error (console spamming):

Quote

[23:44:24] [Server thread/WARN] [FML]: MrTJPCore loaded a new chunk [-50, -125] in dimension 0 (overworld) while populating chunk [-46, -126], causing cascading worldgen lag.

 

After I logged in again, it looked like that: https://imgur.com/a/FrkhZyZ

 

Can someone help?
I'm using Biomes o Plenty and ProjectRed etc.

When my world generates and I fly around, its regulary like that that some chunks glitched into another and I have weird edges ... can someone help me how to fix that?

It only appears when I restart the server. Thats weird. When I start a new world it generates, when I restart the server and it loads new chunks, this error appears. Why?
