Pushing a large commit to a GIT repository hosted on Phabricator produces errors, resulting in the push failing.
Similar errors seem to have occurred with others on T4801, although those are much smaller commit sizes.
- Create new instance of phabricator
- Create a GIT repo
- Create a large commit.
- In my example I've used the android-studio-bundle for windows due to it's large size. It's available at this URL
- This has been broken up into 50MB chunks with 7zip.
