I started getting 
Error: docker sandbox doesn't have sufficient memory available. Please run docker system prune -a --volumes
when starting the sandbox cluster. But there is enough memory according to docker info below. Any ideas?

this seems to happen after I pulled a large image ~ 17Gb. Is the large image causing the issue here?
k
You may have many images in your disk, so you may have to run that command to remove those images
n
is there a limit of image size in the sandbox container registry (localhost:30000)?
below are the images I have

I did a test with following steps: 1. run docker system prune -a --volumes 2. run flytectl demo start 3. check the sandbox is up and console is responding (yes) 4. docker pull an image ~16G 5. when docker almost finished pulling the image in step 4, the sandbox cluster crashed. console isn't responding anymore 6. run flytectl demo teardown 7. run flytectl demo start, and got 
Error: docker sandbox doesn't have sufficient memory available. Please run docker system prune -a --volumes
In the whole process the memory usage is below 30% of total memory. don't know why the images that are saved on disk can interfere with the sandbox cluster and cause the memory issue 🤔

You probably need more disk space on your server; check with 
df -h
and the volume/disk that holds your docker directory
(i.e. the error message is misleading - you're running out of disk, not memory)
n
and docker system prune didn't remove all the volumes for me as in this issue
