SSL + Large file uploads (3GB+)

[FSC]

Hello,

I'm having problems uploading large files (3GB) to a server with SSL
enabled. I'm using nginx 1.4.2 + passenger. Files around 1GB large work
fine.

My /tmp mount is large enough to handle files of that size. I guess I'm
missing something. I read about a SSLRenegBufferSize parameter for the
apache server - is there a similar directive for nginx that I'm missing? I
appreciate any hints.

My nginx configuration:
nginx version: nginx/1.4.1
built by gcc 4.4.5 (Debian 4.4.5-8) 
TLS SNI support enabled
configure arguments: --prefix=/opt/nginx --with-http_ssl_module
--with-http_gzip_static_module --with-cc-opt=-Wno-error
--add-module=/usr/local/rvm/gems/ruby-1.9.3-p392/gems/passenger-3.0.19/ext/nginx


Here is the curl output that I get when trying to post a 3GB+ file:

curl -v -X POST -d @BIG_TEST_ARCHIVE_3.zip https://shared.com
