We finally found the solution and it had nothing to do with GitLab itself. The issue was with the git OS user - it's grace logins have expired. the 'Broken pipe' error with no other errors in the logs was really not very helpful in troubleshooting.
Anyways solved now. Thx a lot for assistance! -- You received this message because you are subscribed to the Google Groups "GitLab" group.
