Broken debian wheezy support

I have a working lxc-container with Debian Wheezy on top on OMV (Debian Wheezy). With the Latest updates, Gitlab Omnibus it's not working. It displaies 502 error so i went to the gitlab-error.log and i found that there is a "permission denied error" in the workhorse socket.

Before I thought that was a lxc-container fault, like SELinux misconfiguration or something like that. So i decided to test a new Gitlab installation on a VM with a standard net install of Debian Wheezy and after the install, Gitlab give me the same error.

If i run chmod 777 /var/opt/gitlab/gitlab-workhorse/socket Gitlab work normally. Any ideas?

Thx for you help and sorry for my bad english

PS: i have only the root account on the machine
