This is caused by unreachable objects being evicted from packs and stored as loose objects for up to 2 weeks, until the next `git prune` run. I think you can avoid this by using `git repack -a -d` instead of `git gc`, but at the risk that a concurrent modification of the repository may result in corruption due to a race condition between the object being needed, and the object being deleted. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
