[Bug] Memory Leak?

Conan Exiles General Discussion
,
1

This bug happens with my dedicated server.
I can no longer keep the server running after the latest bugs.

Environment: Debian Docker Container (Wine) - Pterodactyl Wings - Production branch (Not testlive)
What happens: After some time, could be a minute or two, or it could be a few hours, the server randomly runs out of memory. I can confirm the server has more than enough memory. This happens significantly faster on Siptah than on Exiled Lands but the result is exactly the same, it seems to run of memory while there is still memory available.

Below is a snippet of the end of the server’s log. I am also attaching the full log file, but that is the relevant section.

I would take a look at your modlist and see if there is any mods that are out of date by a few months or longer and try unloading them to see if it works. If that doesn’t work then try loading without mods and then adding them back one at a time.

3

Problem happens without mods too, just takes significantly longer for the problem to occur. When testing i started up Siptah as a example, and after an hour the server ran out of memory. Roughly same error as above.

4

Is that with a fresh database? If so you might try reinstalling the server software.

If possible you might consider trying it on another machine just to rule that out.

5

Problem happens with fresh DB, and also on at least two separate servers.

6

What Wine version are you running? There is an issue with newer versions that causes a memory leak with this game’s server software. I tried different versions until it solved a memory leak issue I was having, and for me 8.0.3 works.

7

Checking. I’ll update in a few minutes after I know what version is in the container. It should be the latest version.

8

The version running in the container is wine-9.0.

9

Try an older version going back until you find one without the memory leak issue on this server software. I can confirm I had the same issue on 9.0. I tried numerous and the one I ended up finding worked best for me was this Wine Proton 8.0.3.

10

Okay i’ll try. I’ll have to build a custom docker container to do so, but i will try a different version.

12

I had to remove the log in the previous post due to the rcon password being in the log. I forgot to remove it. Here’s the wine 9.0 crash on vanilla. I plan to test wine 8.0 and wine 9.16. For now this is looking like a base game memory leak or memory accounting error.
