Docker v3.29 crashing

[abdulocracy]

After updating to the latest release there are the following log errors, LMS later exits with code 139:

Rolled back to 3.28.0 in the meantime, back to functioning normally.

[epoupon]

Arf it was working fine when testing...
Which platform?

[abdulocracy]

Debian 11, Docker 20.10.16, Docker compose 2.5.0

[abdulocracy]

From the compose file:

  lms:
    command: /var/lms/lms.conf
    container_name: lms
    depends_on:
      - traefik
    image: epoupon/lms:3.28.0
    labels:
      traefik.enable: "true"
      traefik.http.routers.lms.entrypoints: "https"
      traefik.http.routers.lms.rule: "Host(`music.abdulocra.cy`)"
      traefik.http.routers.lms.tls.certresolver: "le"
      traefik.http.services.lms.loadbalancer.server.port: "5082"
    networks:
      - web
    restart: unless-stopped
    user: 1000:1000
    volumes:
      - ./data/lms:/var/lms
      - ../music/music-archive:/music:ro

[epoupon]

Amd64?

[abdulocracy]

Yes

[epoupon]

I tested the uploaded 3.29.0 image, it works fine for me.
I also have the error log entry about "Cannot create tables", but it is not important (should be an info).

Do you have more information? Does it crash only when the web interface is accessed? Does it crash at the very beginning?
Can you run with debug log level? (you can provide a custom lms.conf file and set log-config = "*";)

Hi @epoupon @abdulocracy

same issue here after update to the last image version. After quick investigation, I have this entry in my host syslog (the DB UPDATER came from the container, after that it's a kernel issue) :

May 27 14:22:28 ns362699 lms[1143]: [2022-May-27 12:22:28.995] 1 - [info] - [DB UPDATER] Scheduling next scan at Sat May 28 05:00:00 2022

Note the container is restarting, without accessing to the web interface

[epoupon]

Thanks for the valuable information! Indeed I managed to reproduce this by just launching a scan

[rluetzner]

I solved this by throwing away the DB. If you're not attached to the metadata you can try this and 3.29 will work.

[abdulocracy]

Unfortunately since starred tracks can't be exported I can't part with the DB.

[epoupon]

Yes, just stick to 3.28.0, we will eventualy figure out what is wrong with this 3.29.0.
Throwing the DB is not an acceptable solution as the problem is still here.

[epoupon]

I repushed the 3.29.0 and latest images, built this time on Alpine 3.14 as it seems to work as before.
You have to delete your image (docker image rm -f epoupon/lms:latest epoupon/lms:3.29.0) to pull it again

[rluetzner]

I can confirm that the crash no longer happens with the new image. I've restored my old DB from a backup to test this and made sure that it fails again, before I pulled the new image.

LMS is now up and running again, with my old metadata intact. 🙂

[epoupon]

Unfortunately since starred tracks can't be exported I can't part with the DB.

Hope this will be possible soon with #163

[abdulocracy]

Can confirm it's fixed now. Cool theme! :D
