Bundle update “killed:” Watch those log files in your gems!

Today was supposed to be a normal day. A simple pull-request merge, an automated Jenkins build, and then a database migration. What followed instead was a search for the cause of a build failure– or, rather, the cause of a ruby gem that was causing the build failure. The Problem The only hint I had to go on was this message in my Jenkins console: Installing acts_permissive (0.3.2)...
