Third modpack (not a stable modpack overall)

Too long for the comment tell me if you need it

[Faboslav]

Hello, this is probably fault of another mod, can you provide logs while getting unloaded chunks? Is there anything related to friends&foes in the logs?

[zoqin]

Hello, thanks for the answer

Saddly i don't know how to read properly logs I don't know if anything is related to friends&foes in the log but not loading friends&foes fix the issue leading to my theory

Here is a new fresh try (modpack 2+ F&F-2.0.9) (tell me if I can provide more)

log.txt

[zoqin]

Im am leading further experiment (loading in a different order one at a time) and at this point I can say that its not F&Foe that made me unable to load chunk, am I still experimenting to see if its a conflict or if it was pure coincidence that lead to the bug everytime I had F&Foe

Sorry for the false alarme I hope it didn't bother you I will communicate on the mater as soon as I have a better understanding of the issue

[Faboslav]

That's fine, let me know if you find something related :).

[zoqin]

After a lot of experimentation I found that my issue was garbage collection, allocating to much ram didn't triggered GC enough and when it did he would instantly froze the internal server. The only things that change when Friends and Foe was enable was to use just enough ram to trigger GC quickly on my benchmark briking the world generation

Exploring long enough with other mod triggered the same issue once the GC finally triggered

The solution is to lower RAM allocation to trigger GC more often so Java don't froze while processing the high amount of data, I was allocating 20go and I crank it back down to 12go, making other garbage collection optimization would probably help, as long as Java doesn't need to handle 20Go at once

As such I close the issue and thank you for your open mind

Im excited to experience your mod in my custom modpack and to share it with other Have a great day
