All running containers restart on leader reelection

General

Hello,
I wanted to ask - is it okay for docker swarm to restart ALL containers in a cluster after leader reelection? I had a leader dropped by network split, and after reelection (which took 20min!) all running containers got restarted. Is it an expected behaviour?

I know a very long time ago.

Did you find an answer?
I have the same problem, when the swarm leader is gone, then all containers on every node restarts.

Thanks
