Hi Taylor,

Thanks for the swift reply.

It was an emailing mistake. I meant to write

So that the command is reproducible on repeated run.
I must have deleted the remaining part by mistake.

There is definitely connection still, as I can still receive more events after interupting the stuck git command by Ctrl-C.

2.26.0 built from Master git/git

For more info, I have created a paste to demonstrate the bug
https://gist.github.com/sluongng/e14563e4ce3cc9545781ecd5a95169f6
In which, I run `git pull origin` and `git version` on a relatively stale https://gitlab.com/gitlab-org/gitlab.git local copy.

You can get more information from the trace in that paste.
I have annotated the moment which the stuck happened with `It stucks HERE` phrase so look for it.

Cheers,
Son Luong.
