Project housekeeping should remove old objects/pack/tmp_* files
https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/workers/git_garbage_collect_worker.rb
When running git gc
on large repositories it can happen that the process fails and leaves behind a potentially large temporary file inside the objects/pack directory of the bare repository. These temporary files start with tmp_
.
I think the garbage collect worker should remove any file matching that patter older than 24 hours.
