Running ATM7 on a multiplayer server, no changes have been made to the configs or otherwise.
Does anyone know what might have caused this?

maybe there is too much entities in loaded chunks, I had that issue some time ago

1. When did this start occuring? What were players doing when mob spawning stopped?
2. For which mob categories (passive, hostile, ambient, water, etc) did mobs stop spawning?
3. Are no mobs spawning at all everywhere or is it just in specific locations?
4. Does this affect all loaded dimensions or just a subset thereof?
5. Are the mob caps filled? For hostile mobs, that's normally 70 (or 210 to 320 in blood moons) per player. Other mob categories require less than that.
