Occasionally it seems like Garden fails here when Concourse is trying to create a task container.

Hi Concourse friends,
While investigating probably unrelated thing in Garden we managed to reproduce consistently that issue and maybe you would be interested in the scenario.
We created an AWS concourse deployment (if version matters, we used v.4.2.2) with one worker on a t3.nano VM (0.5G of memory) - we really wanted to put memory pressure on that worker. Then we created the following dummy task:
--- image_resource: type: docker-image source: repository: cfgarden/garden-ci tag: '2.0.11' platform: linux run: path: /bin/echo
Then we ran 8 parallel infinite loops running the same task over and over again.
for i in `seq 0 200` ; do echo Attempt $i && fly --target slab-ci e -p -c "<the task yml>"; done
Note that our endless loop runs fine when run in 4 instances
