[DRE-maint] Bug#851570: gitlab: git operations over web causes 502 error

[Libor Klepáč]

Ha, nailed it

we have
worker_processes 1

in /etc/gitlab/unicorn.rb
because of memory constrains

When I increase it to 2, it starts to work.

By the way, gitlab-workhorse is not logging to file, when started over 
systemd, i have to use journalctl to find

POST "/packages-bcom-lib/bcom-lib-cronbuster/create/master": badgateway: 
failed after 61.287s: EOF
