This morning while I was working on one of the client projects, I suddenly got signed out from the site. Simultaneously one of my team member also said the same, he could login. He could get into the login page, but it just loops there, and doesn't go to the dashboard. Also, I wasn't able to log into the CP too, with the admin password.

After a while, few websites started show white screen, and hence I logged into the server using terminal, I can recall I saw some error messages stating 'couldn't create new user due to no space" or something of that sorts.

I manually restarted and ever since I couldn't even get the static websites, no even the CP. I increased the size of the storage by contacting the host.

After some search, I found the docker command to list the containers, and here is it's output.
