Hello,
I have an Ubuntu Jammy container running with Archlinux as the host. I have 64GB of ram but docker is refusing to start any new containers. Before migrating from LXD to Incus i remember setting something to limit memory usage, however i have looked around but cant find anything obvious.
$ docker compose up -d

There is no limit in the incus instance config,
$ incus config show docker1|grep -i limit
There is enough space in /var/lib/docker
$ df -h /var/lib/docker

/dev/zd48 118G 8.9G 103G 8% /var/lib/docker
How do i find out why i cant run a docker container?
I setup a second new ubuntu (noble) instance and setup docker in it. It also gave the same error,
unable to start container process: error during container init: unable to join session keyring: unable to create session key: disk quota exceeded
It seems that incus is limiting memory somehow.
