I'm not sure how to reproduce it.
I have a replica set with 4 nodes running mongodb version 3.2.1 at AWS
i2.8xlarge - linux - database on ephemeral storage
i2.4xlarge - windows - database on ephemeral storage
r2.2xlarge - windows - database on EBS
t2.small - windows - arbiter
I will be happy to explain any other details you might need
