Hello,

I recently moved from the LTS docker image to 2.362-alpine. I had some issues with a plugin being compiled with Java 55, but I don't believe that is related. Once I updated to the new image, it appears the EC2 plugin is now terminating build agents right after they get spawned. Essentially, it spins up an agent, connects, then shuts id down and tries a new one. Rinse and repeat. Nothing on the inf side has changed, and I am able to spin up AMIs perfectly fine by hand. Logs below:
