I'm not sure if this is a MongoDB, Mongoid or Moped problem, but I'm getting massive port usage while inserting into the database.
It looks like that for each insert the driver is opening a new connection to the database, spawning a never dying thread which keeps it's own port open.
The log near the error:

As reported by the activity monitor just before the app crashed:
- mongod Threads: 1716;
- mongod Ports: 1701;
I find it weird that for each insert there's a Adding 127.0.0.1:27017 to the cluster entry.
There are 1022 inserts on the invoice_lines_calls collection before the crash.
This app is running normally at dev/test/staging/production on MongoDB 2.6 + Mongoid 4.
This test is part of the rspec suite, and it was run locally on OSX using (single instance) MongoDB 3.0.4 + Mongoid 5.0.0.beta . All these inserts are running from the same Sidekiq process/job.
Any ideas on how to narrow down the problem? I'm willing dig this up to the bone.
