Root cause and analysis here: https://gitlab.com/gitlab-org/gitaly/-/issues/1656

These files appears when a git index-pack (during a git gc) is interrupted (likely by interactive user action like KILL -9, or oomkiller, or some other guard).

Once the git gc has ended (correctly or not), they are never used anymore (nor cleaned-up by git, which is bad).
They can be removed by hand.

> in rudder, we need to had that to the git maintenance batch.
> we also need to be sure to not start a git gc if another is already running
