Hi, I had a similar problem last week but thanks to some superb
people here it is all solved now.

The problem was (for me at least) that I did COMMIT RETAINING
instead of COMMIT. I got an answer from Helen that explaind the
difference.

I include her answer bellow.

I hope this helps.

It's not a Savepoint (although Savepoints *are* coming in Fb 2). It
is a
full (irreversible) Commit but, instead of closing the cursors
associated
with the transaction, it keeps them open for the new transaction.
Hence,
everything to do with the original transaction and each new one that
is
started after Commit with Retain, using the same cursors, remains
interesting and therefore unavailable for garbage collection.
