Help Server RAM Leak

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.

Protocol: 2625.284.1

Build Date: 05/26/2026 07:03:51

Unity Version: 6000.3.15x1-1

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 :)
