Hi everyone,
I need some help about my cluster swarm.
Since I have upgraded my cluster from three to five manager, I have some tasks of my services that get paused by swarm. I don’t know why and didn’t see anything on the logs.
I need to do a docker unpause to get it fix …
It happens on the same tasks of services every 20 minutes on different stack. All others services work well.
Here my docker version:
