We have any application in our test environment which has 11 services (docker engine) swarmed across 4 servers. During a recent performance test, the only 2 services on one server where both shutdown and moved to another server. They started fine, and other than an hiccup in the performance test, everything continued ok.
But… how can I find out why the services where moved? The application logs and docker logs for the containers don’t show any errors in those two services, they just look like they where shutdown.
