Linux Open Files limit too low error

If you see this error message in the output log file:
2025-07-05T02:57:07 0.058 WRN The open files limit is too low (1024) and may cause crashes. Recommended is at l
east 10240. Follow these steps to increment it:
- Open /etc/security/limits.conf with a text editor: 'sudo editor /etc/security/limits.conf'
- Add or update the line: 'root soft nofile 10240'
- Save the file and exit the editor
- Apply the changes: Log out and back in or restart the system


You need to up your limits file. Basically the game uses 8000 some files loaded in memory to work. You will have random performance studders if you do not address the problem.

in my case I had to add a line in my service file for 7days (/etc/systemd/system/7days.service)

[Service]
LimitNOFILE=10240

I had no luck adjusting /etc/security/limits.conf
adding:
root soft nofile 10240
root hard nofile 10240

Had no effect on the issue

Once I had adjusted the 7days.service file with the one line entry under the service section the error completely disappeared
