[galaxy-dev] Debugging upload via nginx

Hi there

I've got nginx 1.0.5 in front of my Galaxy instance, and I'm trying to get uploads to work as per 'Receiving files using nginx' instructions on the Galaxy wiki. I've added the relevant config to my nginx setup (pastebin http://paste.ubuntu.com/961983/) and universe_wsgi.ini (pastebin http://paste.ubuntu.com/961985/) but it isn't working. How do I debug this? What should I be looking for in the log files? What seems to be happening is that the files are being uploaded - entries are created in database/tmp/upload_store with the contents of the relevant files - but Galaxy is not being informed that the upload is complete.

Thanks, Peter
