Re: File upload stalls: Django + FastCGI + threaded mode

Sorry: in fact, this also happens with prefork mode too.
The only consistent way I can reproduce this problem, is waiting before initiating the upload. Looks like
something wrong on Cherokee or the way I'm configuring it.
I look at the HTTP requests and they look fine. When the problem happens, I see it only transferred the first
few bytes, and then stalls. Tested on Firefox, Safari and Chrome.
I'm completely lost and have no idea how to debug any further. I really need some help on this one, or my only
solution is going back to Apache.

With prefork, I don't see the issue.

Django with prefork got it's share of problems already, so it's preferred to use it in threaded mode. Now I
can't use either, because either I got database problems, or I got those Cherokee file upload problems.
