Cannot push to large repo

[Jookia]

Issue

Impacted version: git master with my pending PRs

Deployment mode: Standalone app with nginx proxy frontend

Problem description: I cloned the Linux kernel repo to GitBucket then pushed a few commits to it. This fails mid-way through, hanging after 'Updating references'

did you adapted the nginx config, especially client_max_body_size

see https://github.com/gitbucket/gitbucket/wiki/Reverse-proxy-with-Nginx for some examples/samples of configuration

Yes, we did that. In fact, we cranked it up to 16 gb. We even increasted the read and write proxy timeout to 1000 instead of 100, which resulted in it hanging for 10 minutes then giving up.

I think this is on the client side. The server I am pushing from has only 2G of ram. I've tried all sorts of stuff in the Nginx configuration, the one thing that finally worked was

git repack -a -d -f --window=0

Erm... Are you sure this is the right command ?

Cloned linux here, .git is 3.4 gb.
After running this command, .git is now 31 gb.
