I have a web server running Apache 5.1 connected to the DMZ port on the ASA 5510. We have an Oracle server inside our network. I have an open 1521 port between the web server ip and the oracle server ip. when anyone connects to the web server through the web app and tries to create a BOL we intermittantly get an error saying the connection timed out. Below is a copy of the error:
Anyway, we need someone to do some testing to see if we can replicate this error

The ASA is 2 months old, both the web server and the oracle server are running Windows 2003 server R2, this problem only started when we connected the web server to the DMZ 2 days ago. we have 2 other web apps running on the same server connected to the DMZ port, one pointing to a SQL server with no problems and another pointing to the same oracle server with no problems.

Run a debug on the ASA and initiate the connection again and see what happens.

I'd suggest doing this in a time of low usage. :)

Thx, already started that process after submitting the question. turns out the ASA 5510 and its SQL*NET filter has a glitch in the buffer size limit, Cisco had a patch for the device, after patching it the traffic is flowing through between the DMZ and the internal server.
