network thread hitch warning: timer interval of … milliseconds means the server thread that sends and receives game traffic was blocked for that long. During the hitch, player updates wait, so players see rubber-banding and delays. The usual causes are scripts that send too many or too large events, a server thread that is overloaded at the same time, or a server at its CPU limit.
What does “network hitch” mean?
A FiveM server runs several threads. The network thread handles packets between the server and players. A hitch is a moment where one round of work took far longer than it should; the number in the warning is how long, in milliseconds.How to fix network thread hitches
1
Check Statistics
Open Statistics in the sidebar. If CPU is at your plan’s limit when the warnings appear, the server has too little room. See how to view server statistics.
2
Fix server thread hitches first
If the console also shows
server thread hitch warning, follow that guide and run the profiler.3
Look for chatty scripts
Scripts that trigger client events for every player (
-1) every tick, or send large tables, flood the network. Send events only to the players who need them, and only when something changes.4
Remove what you don't use
Turn off Start at boot on Resources for scripts you don’t need, and test again. Turn resources back on one by one to find the cause.
5
Keep FXServer current
Use the Recommended build on Artifacts and keep OneSync on On (recommended).
Could it be an attack or a network problem?
If the warnings start suddenly without changes on your side and players time out, check the Firewall Panel for attacks on your IP. Then open a ticket with a log link: click Share log on the console, which removes passwords, keys and IP addresses automatically.Frequently asked questions
Is a network thread hitch my players’ internet?
No. The warning is about the server’s own network thread. A player with a bad connection gets high ping or time-outs, not this warning.Why do players rubber-band?
When the network thread hitches, position updates arrive late, so the game corrects players’ positions when they arrive.Do more players cause more network hitches?
More players mean more traffic, so badly written scripts hurt more on a full server. Fix chatty scripts before adding slots.Does a restart fix it?
Only for a while, if a script slowly builds up work. Find the script so the warnings don’t come back.Related guides
