Server thread stalling
The server console prints a line like this.
What the console says
server thread hitch warning: timer interval of <ms> milliseconds
What it means
The server thread stalled for N ms. Players feel this as a freeze.
How to fix it
- Note what happens on the same cadence as the hitch — a save loop, a database write, a scheduled job.
- Check for a resource doing synchronous database work on a timer.
- A single hitch after a restart is normal warm-up; a repeating one during play is not.
When it is not this
One hitch proves nothing. Startup, a resource restart and a large join all produce a legitimate stall.
