Hi,

Server is getting sync thread hitch warning spam in console.

Because of that lot of players get drop from the server.

We are running following:

  • Operating System: Ubuntu 18.04
  • FiveM version: 3922 Linux
  • RAM - 32 GB and 8 core Intel i9 CPU ( dedicated server )
  • OnceSync infinity

We have optimized our scripts and everything still we get this warning.

Is there any way to debug and find the cause for sync thread hitch warning ?

all my server side code is updated and optimized

Are you noticing any degraded performance in-game server wise?

Usually this isn’t very alarming if you’re so worried about it upgrade your VPS/hosting

it creates huge dsync my vps has 24gb RAM and CPU 10x 3900 MHz

10 is a weird core count, is this a VPS that might be overselling CPU time/doing ‘CPU cycle stealing’?

this is the performance with 65 players

You definitely have something weird going on here, as we don’t have this issue at all with 250 players

Here’s a chart from txAdmin with sync thread

So either (as bubble said) your host might be overselling CPU time or doing CPU cycle stealing

For reference the server this was taken from runs a Ryzen 7 3700x w/ 128gb of RAM, but this is still roughly the same graph we were getting forever ago running a Intel Xeon E3-1280 v3 (roughly a 10 year old CPU) w/ 16GB DDR3 RAM

could it be stream files?

No, Stream files should be Network thread
