I have run out of things to check for and could use some help. We are on a
unix box, CFMX 7, and have started to use the CFDOCUMENT tag.

The tag and code work great in my local environment (windows). I push it to a
dev site (unix) and it still works. I pushed it to production and it fails,
meaning the page never loaded and periodically I would get a null null error.
I did isolate some code it did not like. I had an image that centered itself
on the page using CSS. Our production sites did not like this. Once i removed
that production 2 was happy so we moved the code to production 1, the page
loaded but in a few minutes the NULL NULL error started to appear and then the
server needed to be rebooted. Prod 2 was still working just fine. I am told
that Prod 1 and Prod 2 are identical but yet the error happens on one box and
not the other.

Any ideas?
