how can I fix "Outgoing reliable buffer overflow"?

[whcRkfktlqkfkak]

I have been playing in an unofficial server, suddenly "Outgoing reliable buffer overflow" shows up and kicks me out from the server. When I rejoin, after about 10 seconds or less, same thing would happen. I tried mind wipe tonic, clearing inventory, and even reinstalling the whole game but did nothing. What can I or the admin do to solve this issue?
I played about 50 hours for past 4 days, teleported hundreds of times including awesome teleporter. I also teleported to different maps dozens of times. Could that cause the error?

It is a buffer for messages the server sends to your client. I am unsure if it starts already on the server, or is purely client.

Did the server bandwidth change? (fx hitting a cap so bandwidth gets lowered rest of month, wireless always changing etc).

Did your bandwidth change? (Also momentarily what is available to ARK, fx with 4 people in the house using Netflix at same time).

Do you have staggering low FPS right before it happens?

Do you look at a specific item when it happens? (thinking mainly mod structure or mod dino).

how do I check the server and my bandwidth? I am not really an expert with this kind :)

Also, I don't think there was any mod or dino that caused the problem. I teleported from the island to Gen 2 like 10 times over few hours before I got that error.

Is this happening when you transfer maps? are you modded? make sure you ahve no items on your character when transferring, and too many engrams can also cause it.

"Outgoing reliable buffer overflow" has also to do with your character file, eg. how much engrams you have learned (which is a big point especially if you have mods that add a lot of them), how much is your inventory filled etc. -- this always occours if I transfer between maps in my own, non-official clusters, I cannot prevent this because it seems to be hard-coded. Obviously, official ARK was never intended to have so much engrams learned.

Hint at this point:
Perform a bed's fast travel, whenever you log in to your server or made a map travel. This keeps a lot of trouble away and makes sure that your inventory size is calculated correctly and helmet overlays disappear if you have suitable mods for that.

Another case where this error could occour:
Having big stacks (vanilla setting is suitable) and trying to convert a big bulk at once, eg. you put raw meat in a modded meat spoiler with a stack size of 1,000 & inventory size of 50, and if you keep the inventory open, you'll get that error. 50,000 items converted at once is obviously too much for this buffer.

To know about server bandwidth, you basically have to ask the server admin. They should know the rules for usage etc.

Your own bandwidth. You should know if you are on wireless or plugged in a cable. And if you have a payment plan that means you suddenly get a lot less because you downloaded x GB this period, if you play while everyone else start up their own netflix, have set automatic recorder of 5 different TV stations to start at once and stuff like that.

Personally I have no issues transferring on cluster with armor, hotbar mainly full, bunch of building materials / raw meat or other stuff in inventory. Did close to 300 (unstacked) honey recently. Often do have the max inventory calculated wrong after transfer though (ie I am at 300 and pick up more, it lets me and inventory bugs, have to drop things and relog to get the stuff to show up). Transfer do tend to get my Ark client up above 14GB RAM used, even if play sessions have been short. So if you are low on RAM on computer, this may start make you handle things very slow. (16GB RAM is low for ARK, 4GB* for OS, 10-14GB for Ark, Discord 0.4GB, Skype 0.2 and whatever else you run, Internet Browsers quickly go above 1GB as well with all the advertisement and spyware of today).

If you run low on RAM you want to get rid of as many users as you can. close browser tabs that aren't used right now, close Skype, Discord, close the Steam window etc. NVidia display thing and on Windows 10 dwm.exe can also start skyrocket (at least 5GB for nvidia, like 32GB** for dwm.exe) if computer has been left on a long time, save work then can usually kill them and just keep hands completely off computer till dwm.exe is done restarting - you may lose connections and have crashes due the lag spike, but usually it restarts clean for me.

Also make sure you have lots of free space on swap drive (usually C for Windows) and the drive Ark is installed on, for swaps and temporary files.

Oh, and for the server - the maps use very different amounts of RAM on a dedicated Linux server, if replacing fx Scorched Earth with Genesis 2, the RAM use goes from 11 to 17GB, with very few player bases on. If this error can originate already from the server, changes like this might be the cause of it suddenly happening.


*It is a rough estimate at where the operating systems have what they need to not be slowed down. Some Linux use a lot less, but some that used to be minimal can't even boot with less than 1GB I think it is now maybe its 2. For Windows you need back to Windows XP to have Windows drop to 1.5GB "needed", I don't know what Mac OS really use up, they also started mash their VRAM and RAM together, fanboys seem happy with the performance, I have not seen actual benchmarks, but it definitely changes the profile of RAM use to have fx 16+4 that needs moved between or 8GB both reads from.

**Yes, private set.

It has nothing to do with bandwith IMHO because I play on my self-hosted dedicated servers with the same machine on a gigabit network LAN interface that is plugged to a rock-stable 250 MBit VDSL line with Internet Flatrate -- and I get this error EVERY time I switch the map. Also, don't forget that communication (at least a part) is still routed over Steam servers even if I have everything local.

If you can pick up more than 300 items in your inventory then you've run very likely into that bug you can circumvent by fast travelling directly after each join. This will "reset" weird character behaviours, also such regarding mods.

Low available RAM can be an issue (also low performing HDDs/SSDs will) but usually that's not a problem: the to transferred data are cached onto disk. Therefore, there's set up an extra directory.

Setting SWAP file to the fixed maximum size does in fact have many advantages but I'm sure it won't fix the "outgoing relieable buffer overflow" crash.

It's a long list you've posted but I think nothing of this will help because it's an ARK bug. If your <character>.arkprofile file exceeds a definite size then this error will occour, no matter what -- of that I'm sure.

[Scramble]

Just because you get it somewhere else, doesn't mean bandwidth can not also be a trigger.

The profile file might also bang it every time, doesn't mean there can't be other causes. The engrams have been mindwiped etc. But we can try look at file sizes.

How is it you get your SteamID to find the correct file?

Ok I got bored back here fast. Profile -> Account Details, greyed out small letters.

File is 65,936 bytes for me. No overflow.

[van Grunz]

Sure, poor bandwidth could be a reason, but I've excluded that it's a cause if you have a good one.

My .arkprofile has 236 kB, permanent overflow. It's ridiculous that we're talking about KILOBYTES while we are playing on a game that consumes A LOT OF GIGABYTES...

[Scramble]

How did your arkprofile get that large?

Spend about 4000 points on Engrams, picked up 123 items (not kidding 20 rows + 3, without counting the character score thing), a lot of the items weapons or armor with individual stats. 10 torch skins being the only stacks with same item (4 cryopods having individual timers is counted as separate).

Filesize after afk about half an hour to try make sure its written only increase to 81,581 bytes.

[van Grunz]

It might be due to the mod that let me learn EVERY engram that exists.

[van Grunz]

And I have a lot of "extra" engrams from mods.

[Scramble]

Well inventory doesn't seem to be stored in the profile. No change after dropping most of it off.

[van Grunz]

You can open .arkprofile with a Hex or Text editor. There are the following things stored: Player outfit, possible Hair styles, Hexagon count, Extra Character Levels, all your emotes, all blueprints with full path (!) which is the biggest part in my profile, Genesis Missions with full paths (!) which is the second biggest part, some buffs from some mods.
