Connection is initialized with nil host.

[ptolts]

A connection is being initialized with a nil host. SSL with a 3 host replica set. I modified connection to spit out its options. I can't figure out how to actually reproduce it. Its very random.

"host: port: 27017 timeout: 5
options: {:ssl=>true, :read=>:primary_preferred, :instrumenter=>ActiveSupport::Notifications, :database=>:ptolts}
Completed 500 Internal Server Error in 24ms

TypeError (no implicit conversion of nil into String):"

Looking into this issue further, I think it has to do with the issue Retry on SocketError when calling resolv() #265. It seems it takes down all the nodes if there are DNS issues. Somehow blank nodes end up in the pool and it blows up when trying to connect to one.

I had changed my mongoid.yml file to static ips, but it seems Moped ends up using the data from the Replicaset, not the configuration file.
