Server hang / crash due to svMain watchdog loop and hitch warnings during runtime #3753
Description
What happened?
The FiveM FXServer became unresponsive during normal runtime and was automatically restarted by txAdmin.
The server log shows:
Error: Loop svMain seems hung!
svMain watchdog stack: root
A live hang dump was uploaded to the CitizenFX crash reporting service
After this, txAdmin detected missing heartbeats and force-restarted the server.
Expected result
The server should continue running normally without svMain hanging or the watchdog triggering a forced restart.
Reproduction steps
We have not yet identified what causes this or when it happens. The issue appears to be completely unpredictable and can occur both with many players online and with only a few players connected.
