#18209 `Container ... is not running` error if an docker environment container stops while pantsd is running Issue created by huonw Describe the bug If pants starts a particular docker environment, and that environment dies (e.g. the user restarts the docker daemon or kills the container), pantsd seems to jammed up and emits errors about the container not running or not existing. Pantsd has to be killed and restarted. Reproducer: https://gist.github.com/huonw/95a15c5cac3c5fcaf0aee3f8b63f8116
