Rails - Feb 2006 - Rails controller limits time spent on shell commands?

I''m writing an admin controller for a client with a need for uploading 
_lots_ of images (no, not porn :). I wrote a {gasp] perl script to parse 
jpeg and exif headers and then produce a text file and then a simple 
shell script to upload that text file into the database. The problem is 
that when I run them from a shell, they work and when I run them from 
the web app the text file does not complete. It runs about 80% of the 
way and then just stops. The text file just stops adding characters at 
the same point. It takes about 20 seconds in the web app before control 
is given back to the user.

Has anyone had a similar problem?

Suggestions?
