if you say this worked prior to upgrade (i.e. it worked even though you were
not assigning an IB_Connection explicitly). Then I would assume it has
something to do with creation order. If the IB_Session and IB_Connection
were created before your query, then it may have previously adopted the
default (previously created) IB_Connection.
FWIW, I would always assign an IB_Connection to the query (and perhaps a
transaction) explicitly and not rely on default assignments.
