Experiencing a "rubberbanding until you eventually get kicked" problem with the dedicated server

Hope you don't mind me hijacking your post here into a thread 😅

@subtle cargo I was just about to make a post about this, I am experiencing the same problem with the dedicated server. It seems like we've been able to get away with at least a handful of hours of gameplay before this occurs, but the only way I've found to fix it is to reboot the server.

The best way I can describe it is,

1. The game client suddenly shows "server overloaded", even though the previous 6-12 hours of gameplay were rock solid.
2. Your character movement begins to severely rubberband. After you move forward a couple steps, you immediately snap back to your original position and you are effectively locked in place.
3. After some time, it is likely that you disconnect from the server.
4. No additional players can join the server while this is occurring.

I have experienced this problem now on two entirely different host platforms.

1. My 16-player shared server hosted on GPORTAL (which I'm assuming is a Windows server).
2. My true bare metal dedicated server at OVH (Ubuntu 22.04 + proton-GE).

Different machines, different hosting locations, different operating system, different everything. The only thing in common is the save data and the set of clients connecting to it.

While this problem is occurring, the machine itself does not show any signs of excessive resource consumption. This leads me to believe that it is a problem with the game server software.

@twilit belfry what log data do you have from both your game server and other processes on your system at that timeframe?

time series metrics are helpful to identify root cause when you identify a correlation

check your gameserver log at that time, see if it's saving block data, or if you're using a container image like mornedhels' that uses supervisord and hooks for doing things like live backup/update, perhaps you are hitting an interval with load

or perhaps you have something else running on that server that is less nice than the PID for proton/wine

Also, what do your memory and storage utilization metrics look like at that time interval?

[twilit belfry]

Memory looks very flat and storage has some random spikes, peaking at the blistering speed of a few hundred kB/s, lol.

Going to take me a bit to decipher the logs and attempt to understand what's going on there. Are the timestamps relative? I'm looking for events in the vicinity of 03:12 UTC but I seem to have multiple files that contain that timestamp.

I would see if there’s an in-game thing that is triggering the slowdown, such as a lot of mining/building, objects on the ground, etc. or if this behavior is happening at exactly the same time of day, or after the same exact amount of time- to see if there’s another system process taking your resources.
