By "session", you do mean a TIB_Session, right?

And you *are* using the localhost server when the module's IB_Connection
connects to the database, right?

And you are making sure that the module's objects all point to the correct
IB_Connection and IB_Transaction properties, right? (Don't use <default>
for anything in isapi modules!!)

And, no, the transaction isolation should not have any effect on the
thread-safety of the module. The important thing is to totally isolate the
whole kebab for each instance of the module and to destroy the instance
when it is finished with.
