Accepting a Merge requests does nothing
After pressing the "Accept Merge Request" button, only an button animation is started but no merge is performed.
I noticed that the systemd recipe for starting sidekiq used "-C config/sidekiq_queues.yml" to configure all the queues.
After changing the sidekiq_start_command_args in gitlabhq init script to:
sidekiq_start_command_args="exec sidekiq -c 10 -C config/sidekiq_queues.yml -e ${rails_env} -d -P ${sidekiq_pidfile} -L ${sidekiq_log} $@ >> ${sidekiq_log} 2>&1
All pending Merge Requests start to merge.
