The FiveM warning `server thread hitch warning: timer interval of … milliseconds` means one tick of the server's main thread, which runs your server scripts, took that long. A resource blocked it, usually with a heavy loop, a slow database query or too many events. Record a profile with `profiler record 500` in the console to find the resource, then fix, update or remove it. | Difficulty | Time | Works on | Panel page | | - | - | - | - | | Intermediate | 20 minutes | Every FREAKHOSTING FiveM server | **Console**, **Files**, **Statistics** | ## Is a server thread hitch warning a problem? * **A few warnings at start-up** are normal while resources load. * **Warnings that keep coming while players are online** need fixing. Players notice delays, rubber-banding and slow scripts. * **The number matters.** It is how long the thread was busy, in milliseconds. A one-off warning is usually harmless; a steady stream of large numbers is not. A similar warning names the **sync thread**, which handles OneSync. The approach below works for both. For the network version, see [network thread hitch warning](https://help.freakhosting.com/games/fivem/troubleshooting-network-thread-hitch-warning-in-fivem-servers.md). ## How to find the slow resource with the profiler FXServer has a built-in profiler. Run it while the hitches happen. **1. Start a recording** In the **Console**, type: ```text theme={null} profiler record 500 ``` This records the next 500 frames. Type `profiler status` to see how far it is. **2. Save it** When it has finished, type: ```text theme={null} profiler saveJSON profile.json ``` **3. Download it** Find `profile.json` in **Files** and download it. It is saved in the folder the server program runs from. **4. Open it in Chrome** Open a new tab in Google Chrome, press **Ctrl** + **Shift** + **I**, go to the **Performance** tab and load the file. Long bars show which resource used the time. Details: [Using the profiler](https://docs.fivem.net/docs/scripting-manual/debugging/using-profiler/) in the FiveM documentation. ## What causes server thread hitches? | Cause | Fix | | - | - | | Loops without a wait | Every `while true do` loop needs a `Wait()`. Use the longest wait that works, for example `Wait(500)` instead of `Wait(0)`. | | Slow or blocking database queries | Use the async functions of `oxmysql` and don't run queries in fast loops. | | Looping over all players often | Run the loop less often, or only when something changes. | | Too many events | Don't trigger client events for every player (`-1`) every tick. Send only to the players who need it. | | Outdated or duplicate scripts | Update resources, remove scripts you don't use, and use the **Recommended** FXServer build on [Artifacts](https://help.freakhosting.com/games/fivem/how-to-update-your-fivem-server-artifact.md). | If a paid script causes the hitches, send its author your profile file. ## Is my server too small? Open **Statistics** in the sidebar. If CPU or memory sits at your plan's limit during busy hours even after you fixed slow scripts, the server needs more room. Upgrade in the [client area](https://freakhosting.com/clientarea), or [open a ticket](https://freakhosting.com/clientarea/submitticket.php) with a log link from **Share log** on the console. See [how to view server statistics](https://help.freakhosting.com/portals/game-panel/how-to-view-server-statistics.md). ## Frequently asked questions ### What does "timer interval" mean in the hitch warning? It is how long one server tick took, in milliseconds. A tick should be short, so a large number means a resource kept the thread busy. ### Does a hitch warning mean my host is lagging? Usually not. In most cases one of your resources is the cause, which the profiler shows. Check **Statistics** to rule out a full CPU or memory. ### Does a daily restart help? A restart clears memory that scripts don't release. It doesn't fix a slow script. Set one up in [Schedules](https://help.freakhosting.com/portals/game-panel/how-to-configure-schedules-and-tasks.md) or in txAdmin, not both. ### What is citizen-server-impl in the warning? It is the part of FXServer that prints the warning. It doesn't mean FXServer itself is broken. ## Related guides > **[FiveM server guide](https://help.freakhosting.com/games/fivem/fivem-server-hosting-guide.md)** > > Every FiveM guide in one place. > **[Network thread hitch](https://help.freakhosting.com/games/fivem/troubleshooting-network-thread-hitch-warning-in-fivem-servers.md)** > > The network version of the warning. > **[Console commands](https://help.freakhosting.com/games/fivem/fivem-server-console-commands.md)** > > profiler, ensure and more. > **[OneSync explained](https://help.freakhosting.com/games/fivem/understanding-onesync-infinity-vs-legacy.md)** > > Sync modes and performance. > [!NOTE] > > **Checked by the FREAKHOSTING team** against the official [FiveM profiler documentation](https://docs.fivem.net/docs/scripting-manual/debugging/using-profiler/) on 29 October 2026.
