Mysql2::Error: Lost connection to MySQL server during query

Created by: NotionCommotion

I am operating Centos 6.5 with mysql55.x86_64 , 5.5.36-1.ius.centos6, and installed gitlab per https://github.com/gitlabhq/gitlab-recipes/tree/master/install/centos. I was getting the errors described below. I ended up solving the problem by commenting out "reaping_frequency: 10" in /home/git/config/database.yml. Reference http://www.linuxquestions.org/questions/showthread.php?p=5143596#post5143596 and http://omegadelta.net/2014/03/15/the-rails-grim-reaper/

[root@michaels gitlab]# sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production
This will create the necessary database tables and seed the database.
You will lose any previous data stored in the database.
Do you want to continue (yes/no)? yes
