We deploy replica set between multi location(data center), and We use from mongodb 3.2.
Here is some problems on some machines, The configsvrs after some machines after some minutes down.
We create replica set for configsvr from 12 members, that The replica set have 7 vote for primary and the rest is vote=0 and priority=0.
How to fix my issue?
