I have an LXC container running docker. Many containers are running successfully but I am unable to add more; I am trying to deploy a new docker container and getting the following error:
container init caused "join session keyring: create session key: disk quote exceeded": unknown
But the container has plenty of free space, as does the host. I confirmed this with
df -h and
df -i (so, it's not inodes)
What does this error mean and how is it resolved?
