CPU Utilization at 100 % for a single core (using Docker) on Linux

[AstragoDE]

TShock always uses up 100 % of a single CPU core whilst running.
I am using Docker on Linux.

• TShock version: 5.9.9.0 (commit: f955dd6) using docker
• TShock build number (if known):

Reproduction steps (if applicable)?

1. Start the server using docker compose
2. Look at the CPU utilization of the server

compose.txt

Any stack traces or error messages (if known)?

No

Any screenshots?

Any log messages from files that end in .log or .txt? What are the last 100 log messages from the server console?

What plugins and what versions of those plugins are you running?

No Plugins

If I didn't provide any logs this issue, please close my issue immediately. I'm sorry for the inconvenience.

yep, can confirm, doesn' matter if its docker or direct run
cpu usage is 100% per 1 core since player logs in

Same, Debian 13, .NET 9, TShock 6 Beta, server is empty

[odcold]

yep
adding

 tty: true
 stdin_open: true

to docker-compose.yml
fixes the issue

I think as of TSAPI#270 this should be improved (will be out in the next release, but not available in this pre-release (B) out now).

See graphs: Pryaxis/TSAPI#270

Should be improved in https://github.com/Pryaxis/TShock/releases/tag/v6.0.0, please let us know if it is not.
