Sequelize: TimeoutError: ResourceRequest timed out : <p>My Express app running on node 6.11 with Sequelize 4.5.0 will sometimes throw <code>TimeoutError: ResourceRequest timed out</code>, on operations that should not be particularly expensive. We're talking 5 rows of writes, each executed individually.</p>

<p>The database is an Amazon RDS MySQL instance, that hasn't shown any problems connecting to our second API that is written in Ruby and is using ActiveRecord as an ORM.</p>

<p>I'm not sure how to begin diagnosing the problem, any ideas on what I should do next?</p>
