We do client side partitioning by day, because we need to be able to remove lots of data quickly. With this scheme we run into all sort of bugs in mongos. This seems to be the latest one. The application gets "setShardVersion failed" when it attempts to write to a database that has been dropped.
The application is designed to not do this by periodically checking which databases exist and making sure to write only to those that exist. Still, and presumably because of SERVER-1726, it gets the names of databases that in fact do not exist, and subsequently when it tries to write to these it gets errors back.
This is from the mongos log:
