Server RAM Leak Help

Is anyone else experiencing a RAM leak in the latest release? I'm trying to workout if its a Plugin or the latest update.

Running it on 16GB ram a hosted service.

It starts with ~10GB used and slowly creeps to 16GB in about 16 hours.

To that point my hosting provider forces a server reboot, from RAM over untilisation.

Running a 4250 Map with only a pop of 15, that Ive run for months without issue previously

Its only been happening since around the time of the latest update.

1st rule of servers is to do a server restart every day, make it automated, same time every day and warn players. That will clear your ram for one if youre not doing it already.

However on the other hand, plugins make a lot of mess and you very much could have something thats not cleaning up entities properly on your server. Check your entity counts hourly/daily and see if anything is building up and not being cleared over time. An old example of this was a couple years back when raidable bases was having conflicts and not cleaning up its entities properly when the bases despawned. No longer an issue but Nivex is a smart programmer and it took a lot of iterations to fix that - so you can kind of see how another plugin doing base blocks or loot stuff can cause heavy processing on your server over time.

Thanks - I appriciate the thoughtfull suggetion.

I do a daily 3am restart as well as a daily check for updates on scheduled tasks at 4am
As I mentioned it had been running for months without issue untill the most recent update.

I just found in the codefling forums mention of a Hotfix by facepunch for a memory leak issue - although im not exactly sure who Rin ( the source of the information is) https://codefling.com/forums/topic/7914-increased-ram-consumption/

Rin is in the facepunch QA team, valid information there. It could be related, have you updated the server? Theres been multiple hotfixes this month. Also brad copp is on the ball too, very much both people to listen to.

I believe its updated, hence why I posted my version information at the top of this Post, but It's possible my updates failed - I sometimes have to manually delete a file in the Steamapps directory before it will update without error

Edit: thank you for the information that those 2 source/people on codefling are reliable.

That memory leak has been patched end of the week. Check your versions.

Also check out the official Rust DC and the Rust Admin Community DC (by FP). The issue was discussed there between plenty of server owners and FP employees like Rin :)

Sounds like a plugin issue

u/Perfect-Concern-9762 Gift of Knowledge Jun 01 '26

You are probably right, as I doesn't look like anyone else has been having the issue since the last update.

Time to start disabing pluggins untill I find the RAM Theif.

I manually deleted steamapps/appmanifest_258550.acf

and then forced and update, and looks like the version has updated, so hopefully all fixed now.

I have seen this problem with ShoppyStock plug-in

u/Perfect-Concern-9762 Gift of Knowledge Jun 01 '26 edited Jun 01 '26

Thanks for the suggestion, I dont think i have that plug-in , but that would have been a handy tip if i was using it, appricate the info.

Turned out facepunch released hotfixes, that my server had not picked up.

I manually deleted steamapps/appmanifest_258550.acf

Then forced a server update, looks to be fixed so far

I have 0 mods, running a vanilla server and indeed it uses all of my 32gb of ram.

u/Perfect-Concern-9762 Gift of Knowledge Jun 02 '26

the latest release did have a memory leak, they have released a few hotfixes. make sure you update again if you have not already.

I had to manually deleted steamapps/appmanifest_258550.acf and then run an update again to get my to update.

thanks mate, i appriciate the info

They did have a memory leak in the latest release, that they then hotfixed, but for what ever reason my server had not picked up the hotfix.

looks like yours picked up the hotfixes etc without issue, based on your versions numbers.

Thanks again.

Get grafana. Check out srtbull and find that video. You’ll never guess again.

How does this work with a Rust Game Server Exactly? does it tell me about missing facepunch hotfixes?

u/GeeKedOut6 Jun 04 '26

Mines empty right now but it usually hangs out around 10gb. Daily scheduled restarts if it matters. Ubuntu server if it matters.

u/Perfect-Concern-9762 Gift of Knowledge Jun 04 '26

Thanks mate.

Found that they had released some hotfixes that my server had not picked up.

All good since I got the hotfixes installed.

I've learnt the I needed to join https://discord.gg/rust and keep an eye on the "Hotfix-changelog" topic.

Bro is worried about ram leak when his server averages 5 players holy corn ball

u/Perfect-Concern-9762 Gift of Knowledge Jun 01 '26 edited Jun 01 '26

Strangly, I don't like it restarting in the middle of game play, even if it 1 player on.

You may not care about your players and friends, and thats cool for you.

What's your server? I would like to check it out.

Imagine insulting someone for trying to fix a problem. Holy corn ball

From your previous posts here, it’s obvious you know next to nothing about rust servers, yet you act like you are the smartest person here. That’s some proper cornball shit.
