502 error stays on forever

hi all,

brand new install (latest) on fresh ubuntu 14.04.

all services seems up :

$ sudo gitlab-ctl status
sudo: unable to resolve host Talend-GIT
run: gitlab-workhorse: (pid 974) 625s; run: log: (pid 965) 625s
run: logrotate: (pid 972) 625s; run: log: (pid 963) 625s
run: nginx: (pid 976) 625s; run: log: (pid 964) 625s
run: postgresql: (pid 973) 625s; run: log: (pid 966) 625s
run: redis: (pid 975) 625s; run: log: (pid 967) 625s
run: sidekiq: (pid 977) 625s; run: log: (pid 968) 625s
run: unicorn: (pid 2409) 10s; run: log: (pid 962) 625s

“top” shows a process called “bundle” that takes a lot of CPU and the pid changes every few seconds. when i browse to the ip of the server, i get the 502 page (which loads very fast) but git will not start (see attached).

did “gitlab-ctl reconfigure” a couple if time, went through with no errors.
any ideas ?

This is the process :
