RE-occurring server crashes

Hello,

I am running Tekxit 3 Modpack with a small group of friends. The server crashes often while we are loading in new chunks, but sometimes it occurs randomly as we are stationary. The crash occurs with 2 or even 1 person connected.

I would appreciate any help we can get! Thanks.

LOG: https://mclo.gs/I738KRu

This error pops up a lot:

[05:19:36] [Server thread/WARN] [FML]: DungeonTactics loaded a new chunk [155, 31] in dimension 0 (overworld) while populating chunk [155, 30], causing cascading worldgen lag.
[05:19:36] [Server thread/WARN] [FML]: Please report this to the mod's issue tracker. This log can be disabled in the Forge config.

Your server is overloaded

Is there anything that will prevent this from happening? Thanks.

For modpacks, not really.

A mod/modpack might run just fine when you started to use it. But it can brake at any time. Cause the more you use it, the more RAM you need, and since aternos has a RAM limit (Cant rly complain, its free) then it will eventually give up and start to crash.

This is frustrating. Why do you offer modpack installation to begin with?

I appreciate the free server hosting, but there's no point when people can't maintain a solid connection.
