Server Crash with bad file descriptor

I have the problem that one of the my server crashes after a while. My other Servers are running without any problems. I think this has something to do with the error in the last line, but I am not sure.
This is the Log: 2020-02-03 17:12:32.407135|INFO |ServerLibPriv | |TeamSpeak 3 Server 3.11.0 - (Sorry I can’t get the text correctly formatted in the forum.)
And I did a post in the old forum: TeamSpeak - Official TeamSpeak Community Forum


Please ensure that /dev/shm is properly mounted

The output from “df -h” is:

udev             32G     0   32G   0% /dev

tmpfs           6.3G     0  6.3G   0% /run/user/1000

so I think its properly mounted. And 3 other Servers don´t have a problem.

Maybe you updated the server incompletely.
Make sure to overwrite all server files in order to update the server.

A week ago I completely deleted and reinstalled the server. So this should not be the problem.

2023-05-18 20:46:02.686424|ERROR   |Accounting    |   |failed to register local accounting service: Bad file descriptor

recently our license expired and since my colleague had removed the license key file, so my question what must go instead?

& where do we get the “standard” licenses from?

We are using: DOCKER-COMPOSE

So, still there is the problem that the server crashes, with the same message.

My technician gave me the following to post here on the forum:

    image: teamspeak
    restart: unless-stopped
    network_mode: "host" 
      - 9987:9987/udp
      - 10011:10011
      - 30033:30033
      - /root/docker/container/teamspeak:/var/ts3server

      TS3SERVER_DB_PLUGIN: ts3db_mariadb
      TS3SERVER_DB_SQLCREATEPATH: create_mariadb
      TS3SERVER_LICENSE: accept

any infos to this problem?

→ my technician use the following website: Docker

everything done/ available (according to technician)

our mounts:



I don’t think our problems are related. But maybe they are, so I share what I did to solve the problem: I had 4 different instances of the TeamSpeak Server running. 3 of them with the same License and one without a License. Then the Server without License started to crash.

I then requested an expansion of my License to 4 Servers and gave this Server also a license.
At the same time, I moved all of them in one Server instance with multiple VServers (or how ever it is called)

Maybe it will help you… or give you an idea for what to look :smiley:

we found this issue from 2019…

related to this solution: low memory ??

issue is still present… looks like not interested in fixing this…

All answers and information are given in the GitHub issue you did link.

Memory must be available and /dev/shm must be available all the time.

Not a Linux pro answering:
Not having any space on swap may cause issues. Doesn’t have to, but it can happen.


issue still not solved, RemoveIPC=no in systemd config didn’t help. shm is mounted and has enough free space. Teamspeak Server is latest available version, but keeps crashing once a week. Please fix.

Filesystem      Size  Used Avail Use% Mounted on
tmpfs              16G  1.7M   16G   1% /dev/shm

also enough free memory:

                      total        used        free      shared  buff/cache   available
Mem:            30Gi        14Gi       1.2Gi       3.5Gi        15Gi        12Gi

any infos on this crash?

Not a crash and all answers we can give at this point have been given.

So only running in circles.


Alright thx!
