Those threads are [waiting](https://github.com/jeremyevans/sequel/blob/b6fba8389140f1c4307f83503cf9f3a14e26ebf4/lib/sequel/connection_pool/threaded.rb#L147) to obtain a connection to the database. It could indicate a connection leak, a loss of connectivity to the database, or some connections getting wedged. I do not have a database with which I could test how to diagnose that.

I cannot be sure, but I don't think you are hitting issue #27.
