I have this configuration for test servers (the order of the instance
start leads to this conf.) not for production.

I'm pretty sure this won't affect the issue you've mentioned, but it's
worth pointing out.

If this is really how you've arranged your shard replicas, your system
cannot survive a failure, because you've got both replicas for each
shard on the same server.  If that server dies, half of each collection
will be gone.

Thanks,
Shawn
