Starting the following contraption: https://imgur.com/a/gjVdtET
The server crashes with different crash logs, but same server log
therefor the server log: latest.log https://pastebin.com/7HtJ3Fk1
The two crash logs:

• https://pastebin.com/P4Qzju9c note: it says "ServerHangWatchdog detected that a single server tick took 60,00 seconds[...]", but it crashes immediately without a 60s time window.

This issue has been closed since it has been inactive for 3 weeks since it was marked as stale.

I want to follow up with a similar report. Idk if I should open a new issue or not, as this seems to be the exact same issue. I have a logging saw/deployer minecart contraption for wood collection running continuously, and the server eventually crashes with "ServerHangWatchdog detected that a single server tick took 60,00 seconds[...]" as above.

Once this happens, even after server restarts, the server is unable to be connected to. When any client connects, it immediately hangs again.

heres a debug.log leading up to one of the crashes, nothing of note really: https://gist.githubusercontent.com/phyne/224d440f9f484fba5088c665a4a1ce25/raw/7afb15fe925111eefd38dbd47796ee12bbe9296f/debug.log

Forge 1.16.5-36.0.13
Create v0.3e

The server has been running continuously without error for about a month with windmills, crushing wheels, elevators, etc, and it's seemingly this particular contraption that is causing the issue.

I end up removing the create mod, letting the server delete all running contraptions, then reinsert the mod, and the server runs OK again.

EDIT: I'm actually thinking this is performant after some further looking around at mod issues. I'll update when the servers been running well for a bit without performant.

EDIT: I'm actually pretty sure im terribly wrong, and its not this. I have no idea what's causing it and were a solid month into our playthrough. massive headache...

EDIT: after a whole round robin of stress testing and removing different things, im almost certain again its a minecart contraption with a deployer thats causing it!
