We obviously don't have access to all the data you have available, but
from what's been stated, your conclusions are not justified.  It would
be nearly impossible for Tomcat (even the five-year-old, horribly out of
date version you're running) to cause this kind of problem.  It is much,
much more likely to be something subtle in your app, such as inadvertent
data sharing via static or singleton variables or storing data in the
wrong scope (e.g., request-specific items stored in a Session object).

There is a very small chance that the problem could be any of the
following, but you didn't bother to tell us what they are:
1) JVM (what level & vendor?)
2) OS (what level & vendor?)
3) data base (what level & vendor?)
4) JDBC driver (what level & vendor?)

Since you used the term "JDBC Data Bridge", I fear you may be using the
ancient ODBC bridge to some flavor of Microsoft data base (Access?).  If
so, both ODBC and Access have long been proven to be completely
inadequate for any form of production use.
