A few days ago, one of my servers that was hosting a community edition of Gitlab rebooted (because of a hosting provider maintenance). Since that moment, that GitLab instance is partially broken : sidekiq completely refuses to start.
It restarts in an endless loop, with the following trace in the logs (from gitlac-ctl tail):
==> /var/log/gitlab/ci-sidekiq/current <==
2016-08-29_11:07:56.79639 bundler: failed to load command: sidekiq (/opt/gitlab/embedded/bin/sidekiq)

The problem occured on GitLab 8.5 (If I remember properly). I tried to uninstall the Omnibus package and update to the latest version (8.11), but it did not fixed the problem.
I checked by hand, the reported file (/opt/gitlab/embedded/service/gitlab-ci/Gemfile) do not exists. Running gitlab-ctl reconfigure also did not fixed the problem.
I'm really not familiar with Ruby ecosystem, so I'm asking for your help. Have you any idea how I can tackle this issue ? (I can provide more logs / informations if you think something relevant is missing).
I don't know what the answer was but as I was in a hurry, I switched to a the docker installation of GitLab which solved the problem (as well as bringing more isolation in my setup).
