Additional context
This normally occurs when people start exploring new Chunks, and when there is 2 or more players.

It seems recurrent complex is trying to generate structures, but with several people exploring at once, and no pregenerated terrain. It's taking too long so the server stops automatically after hanging for 60sec.

Yep, what Nazta said. Set player-tick-time to 0 in serverproperties :)

What is "player-tick-time" though?

Edit:
Nvm, I believe you meant the "max-tick-time" setting.

Yep :) my bad.
