A primitive way to confirm it is the odbc driver- use 2 web browsers to 
make 2 requests at the same time. Or use a benchmarking/stress testing 
tool to simulate many requests at the same time (like siege or similar).

To eliminate the problem - you may need to synchronize all database 
access so only one request may view/fax/whatever at a time. Or get a 
thread safe version of the odbc driver.

After that - its out of my league.
