I agree. To clarify my layout, my clients connect to my middle tier
via tcp (custom protocol that rides over http specifically). There are
no per-user or per-seat licences for the middle tier framework. The
error I am getting is being thrown in TIB_SessionBase.HandleException,
which is called when TDataSet.Open fails. I believe that the framework
is using a TIBOQuery at the time the call fails.

The exact error I get is:

Project GlobalServicesServer.exe raised exception class EIBO_ISCError
with message 'ISC ERROR CODE:335544327

ISC ERROR MESSAGE:
invalid request handle

STATEMENT:
TIBOInternalDataset: "<TIBOQuery>.<TIBOInternalDataset>."

'. Process stopped. Use Step or Run to continue.
