git push with ssh causes remote end to hang up

I encounter the same problem as Issue BCLOUD-6406.

git push is stalling out on large files:

$ git push Counting objects: 3755, done. Delta compression using up to 8 threads. Compressing objects: 100% (3708/3708), done. Writing objects: 9% (334/3708) <- this never ends

environment is windows/Git-1.8.3-preview20130601.exe.

Searching the internet - it looks more that a missconfigured sshd is on your side. Please check!
