Yes, that's expected behaviour. The container is locked while it's
being stopped. The lock blocks other commands from using the
container.
i agree. there are actually several operations like stop where this can
happen.
I am optimistic that we can improve the locking and introduce an
intermediate state between "running" and "stopped" and unlock the
container. I am pulling Matt Heon who likely has the best
understanding how we can achieve it.
Matt, what do you think?
Kind regards,
Valentin
