Hi list

My topology is :

client ---> nginx 1.6.2 (port 80) ---> nginx 0.7.69 with mogilefs module (port 2080) ---> mogilefs .

I want to upload a 8G file to mogilefs , the uploading URL is
http://dfs.myclouds.com/upload/glance_prod_env/d29a0a4a-7888-487e-91b5-57e9bbf351e7
There are errors , I have enabled debuging in both nginx instances , but seems that they are not detailed enough.

My question is that :
How can I find out what cause this problem "upstream prematurely closed connection while reading response header from upstream".

Thank you !
