Gitea stopped running (due to database error "Got an error reading communication packets")



Gitea worked for some weeks, but suddenly stopped working yesterday (or maybe some days before). I’ve running it within docker

version: “3”

external: false

image: gitea/gitea:latest
- USER_UID=1000
- USER_GID=1000
restart: always
- gitea
- ./data:/data
- /srv/services/git:/persistent
- tmpdata:/tmpdata
- “8083:8083”
- “2222:2222”
- database

image: mariadb
restart: always


- gitea
- mariadb:/var/lib/mysql

I now get these database logs:

Last lines repeat endlessly and I can’t connect to the webinterface.
If I connect to the docker image with exec and try to do selects within tables everything works fine.

The only thing which comes into my mind, what I’ve done the last days is following:

  • I did a fresh install on my host system 2 weeks ago and 2-3 days ago I noticed that utc-time was still set, so I changed it to my local time.
  • I did also a reboot, to see if this does change something.

Any help is appreciated,


Problem solved:

  • I moved /data/gitea/ssh/gogs.rsa some time ago on my host and since I did not reboot until now, I didn’t notice the problem.
  • within docker, there were problems creating a new /data/gitea/ssh/gogs.rsa (actually ssh-dir was not writable within docker)
  • Though it’s somehow funny that massive loads of connections are opened to database (and it seems that they are not closed properly), bringing my small fileserver dual-core atom to more than 120% CPU-usage (a whole and a part of another core) …


Thanks for sharing your Dockerfile. Question. How are you managing your DB password? Is that kept in the Volume you’re using our somewhere else?


The file I’ve shared is a docker-compose.yml and I have a .env file in the same folder, which consists of simple key-value pairs (


docker-compose.yml (and possible small bash scripts) of all my docker-containers are backuped/versioned within git/gitea on my fileserver, since they are themselve passwordless I can save them anywhere, but .env is never stored anywhere else than in the same directory as docker-compose.yml and only accessible by root. In case of harddiskfailure I’ll have to recreate them manually.


That’s a solid approach. Thanks for sharing. If you care to write it down I’m happy to provide you a static wcms solution which scales with your traffic.
