TFS Git 2013 Repo Corrupt

Question

Hi,
We just migrated to TFS Git and our server version is 2013 Update 4. It, in turn, is using SQL Server 2012 SP1.
One of our git repos has been corrupted somehow and we are trying to understand what happened. When we try to fetch or pull, we get this error:
remote: Microsoft (R) Visual Studio (R) Team Foundation Server
remote: Found invalid data while decoding.
fatal: protocol error: bad pack header
We are trying to work out what the cause of the problem is so it doesn't happen again. Can anyone point us in the right direction?
Some additional information: We have Mac, Linux and Windows git clients using this repo. Also, we have binary files in the repo and we frequently use merges and pull requests. You can still do a git clone --depth=1 --single-branch and then do a git fetch
--unshallow successfully on the all but one of the branches.
Update: This seems to be related: https://social.msdn.microsoft.com/Forums/vstudio/en-US/648d24fd-53bd-40b4-b47b-2c0e9cd8f30c/tfs-20132-git-clone-fails?forum=tfsversioncontrol
Thank you!

Hi Johannes，
From your scenario and error message,  you might run out of memory on the server which can be caused by the reasons below:
A repository with lots of large files, which can cause re-packing to take a lot of memory.
Limited virtual memory - either in general, or just for that account due to the
ulimit setting
And you can execute the git command on your server machine to get it resolved, the commands are:
git config --global pack.windowMemory "100m"
git config --global pack.packSizeLimit "100m"
git config --global pack.threads "1"
command You can refer to the links below for more information about the solution when get git repository udpate:
