Hello all…

Wonder if someone can shed some light on this. I’m trying to implement  
a multi-file upload using a Java based uploader called  
“Aurigma” ([http://www.aurigma.com/Products/ImageUploader/](http://www.aurigma.com/Products/ImageUploader/)). Its a  
widely used component, you may have seen it on Facebook…etc. What the  
tool does is perform multiple file form posts to a hidden page. In the  
past I have successfully used this tool in PHP without any issues.  
However when trying to implement this with Ruby and Mongrel, I seem to  
be running into a “Too many files open” error when trying to upload  
more than 5 files. I know there are limitations with mongrel on its  
own. I have to assume once in production and Mongrel is being proxied  
via Apache, passenger…etc that maybe this will be less of an issue,  
but not sure. Before I start configuring apache to test that theory, I  
figured I post this issue here and see if anyone has had a similar  
issue.

Thanks…

I might be writing nonsense but have you tried to modify the “pool: 5”  
to something else in the database.yml file?

Cheers.
