I have a situation where multiple docker daemons stopped on separate AWS instances in relatively close time frame (all in the same 45 minutes, two in the same 10 minutes).
There appears
Stopping Docker Application Container Engine...
in the logs without any previous event.
It is followed by
level=info msg="Processing signal 'terminated'" level=info msg="ignoring event" module=libcontainerd namespace=moby topic=/tasks/delete type="*events.TaskDelete"
and finally
Stopped Docker Application Container Engine.
after what Docker Daemon has to be started manually.
It happened before in one system but now it appeared in 3 systems simultaneously.
Application logs do not indicate anything suspicious.
Does anybody have similar experience? I am wondering at the moment what steps I should take to have more information during next such event.
