Increase core.packedGitLimit When core.packedGitLimit is exceeded, git will close packs. If there is a repack operation going on in parallel with a fetch, the fetch might open a pack, and then be forced to close it due to packedGitLimit being hit. The repack could then delete the pack out from under the fetch, causing the fetch to fail. Increase core.packedGitLimit's default value to prevent this. On current 64-bit x86_64 machines, 48 bits of address space are available. It appears that 64-bit ARM machines have no standard amount of address space (that is, it varies by manufacturer), and IA64 and POWER machines have the full 64 bits. So 48 bits is the only limit that we can reasonably care about. We reserve a few bits of the 48-bit address space for the kernel's use (this is not strictly necessary, but it's better to be safe), and use up to the remaining 45. No git repository will be anywhere near this large any time soon, so this should prevent the failure.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
