I have a Ruby on Rails 5.0 application. The server complained that it was missing a Javascript engine so I installed node.js. Now, periodically, node will kill our server with CPU usage. We use MongoDB, ElasticSearch, and Rails 5.0.
Any ideas how Rack or Rails, or Mongo or ES use node? And any ideas on how to troubleshoot. We don't have any direct node calls in our code, it's all just infrastructure calls.
