If your IntraWeb application is multi-threaded, than it is important,
that you have a TIB_Session in your datamodule. From the online-faq:

One thing to ensure is that each thread needs to create a TIB_Session component. Then, when you create the other components, like the TIB_Connection, make that TIB_Session instance the owner of the other IBO components the thread uses.
Make sure the TIB_Session is FIRST in the creation order.
