Getting 502 on gitlab when adding repositories, users or doing other actions

Question

Usually fixed by refreshing (re-sending POST) the browser multiple times.

# sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production

The server itself has 4GB RAM available and multicore cpu. The error comes instantly so it does not seem to be an memory or timeout problem.

I posted the bug here: https://bugs.ruby-lang.org/issues/10872 but it was closed as invalid.

I have no clue how ruby works so no idea what I am looking at or looking for.

For future reference: turns out GitLab does not run on Debian 7 32Bit - I can not say for sure, but doubt it has to do with the versions in Debian's 7 repository (which are in general older) as I compiled most of the stuff and with gem it anyway got the versions as defined by GitLab.

Very likely GitLab (or gems it is using) does not currently work on a 32Bit system.
