I have a problem similar to the one described here: http://forum.nginx.org/read.php?2,41892,42433,quote=1 - I'm seeing some "client closed prematurely connection" errors. They seem to happen constantly for one of our users, who is using the same software as everyone else (browser plugin to upload files), I can't reproduce it and I don't know a lot about server configuration. Can anyone help me to find out what the problem is (or even if there is a problem)?

Nginx version 7.64 running on Ubuntu.
