Unable to start mdns: Out of memory

[Jejebond]

Hi !

I've got an issue. The container won't launch. I've tried a lot of stuff. It stopted working on 04/25 around 6pm. Probably due to the update. The terminal says :

Unable to start mdns: Out of memory

My Docker compose :

services:
  ser2net:
    container_name: ser2net
    image: ghcr.io/jippi/docker-ser2net
    restart: unless-stopped
    network_mode: host
    ports:
      - 20108:20108
    volumes:
      - /volume1/docker/ser2net/ser2net.yaml:/etc/ser2net/ser2net.yaml:ro
    devices:
      - /dev/ttyACM0

My ser2net.yaml file (used for Conbee2 dongle on Synology NAS with Home assistant) :

connection: &con01
  accepter: tcp,20108
  connector: serialdev,/dev/ttyACM0,115200n81,nobreak,local
  options:
    kickolduser: true

Thanks

Can you replicate it with any of the previous tags?

[Jejebond]

Thanks, you are right, it's not linked to latest tag. 4.6.1 has the same issue. Can't figure out how to fix this. Still, it used to work before. Can't see what has changed then...

#cminyard/ser2net#63

Similar issue but -d parameter, as sugested, is already set.

[jippi]

Does it happen on 4.5.1 as well?

[Jejebond]

Same on 4.5.1

I was able to update multiple times. But this time... something changed with Portainer ? I'm a beginner at docker stuff.

[jippi]

I don't use Portainer, so can't speak to any changes within that ecosystem - does it work if you increase the memory limit for the Portainer container?

[jippi]

At a glance, it might be an upstream issue in the mdns library - googling leads to multiple resources mirroring the experience described here: espressif/esp-idf#13333

[jippi]

I don't think this is a jippi/ser2net or Docker issue; I can't reproduce it on my Raspberry PI, Mac, NAS, or home lab servers (across arm and amd64 architecture) - going to close the issue - but feel free to provide more info, debug info, etc. in here

I just pulled this container for the first time and hit the same issue on an rPi, happy to provide any details i can

version: '3.4'
services:
  ser2net:
    container_name: ser2net
    image: ghcr.io/jippi/docker-ser2net

log

Unable to start mdns: Out of memory

given i don't need mdns for my application can i disable that in someway?

---edit---
oh its a non critical error, the ser2net functionality still works, confusing but ok :-)
