Hi,

We just push a patch on our server. The patch actually require from our Gemfile a git repo using a specific branch as follow:

gem 'valid_email2', github: 'wamland-team/valid_email2', branch: 'feature-mx-whitelist'

When restarting the server, and especially unicorn; we’ve got the following error in the log:

E, [2016-12-12T19:56:39.640894 #30255] ERROR -- : reaped #<Process::Status: pid 30522 exit 1> worker=1

NOTE: We did ran bundle install during the deploy.

Idea? Thanks
