Andrew, I can't help thinking the code you haven't shown is important. Are you creating a CF thread? And are any of your variables in shared scopes? Transactions and threads don't necessarily work the way you might expect. There are lots of possibilites for cross-talk between threads, connections and transaction in a CF thread scenario, particularly where shared scopes are involved.
