I found a vulnerability in docker of the latest version which could cause a Denial of Service, it results in a machine could not join the swarm cluster after another node's repeatedly joining and quitting the swarm for many times (taking my testing as example, it should need at least one thousand times). Moreover, the docker debugging info indicates the Dispatcher is stopped and ca server may exited sometimes. Login machine A1 and join the swarm ,and then quitted the swarm. Login machine A2, repeatedly join and quit the swarm for 1000 times. After finishing that, Login machine A1 again and attempt to join the swarm, it failed. Error response from daemon: Timeout was reached before node was joined. Attempt to join the cluster will continue in the background. Use "docker info" command to see the current swarm status of your node. level=error msg="failed to remove node" level=error msg="session failed" error="rpc error: ... context canceled" level=debug msg="heartbeat expiration" level=error msg="failed deregistering node after heartbeat expiration" error="... dispatcher is stopped"
