I’m having great difficulty in finding a bug preventing some uploads to  
my rails app through Uploadify.

Here is the error I’m receiving:

[http://j.imagehost.org/0353/uploadify-errors.png](http://j.imagehost.org/0353/uploadify-errors.png)

The thing that’s making this difficult is that it’s not at all  
consistent. Sometimes the images will upload perfectly fine. Other times  
they won’t. The same image(s) that fail on one attempt will succeed on  
another. I really can’t understand it, and I can’t find any information  
from the web about it. The problem persists across browsers, operating  
systems and users. Sometimes it works, other times it doesn’t. In any  
given list of images to be uploaded in one go, it’s possible that all  
will work, all will fail, or some will work and the rest fail.

I’ve updated all the related software to latest releases (except Rails,  
running 2.3.4 there). Paperclip and Uploadify are running latest  
releases.

If anyone has any advice on where I need to start looking I’d really  
appreciate it. If you need any other information from me, just let me  
know what and I’ll get it.

Thank you very much.
