Vlad,

it's a little bit difficult for me to reproduce this bug. It occurs
on a 24h/7d system from time to time, and my client will not be very
happy to let me use it for testing purposes (my workaround works fine
now); otherwise I would need enough PCs or VMs (>10) running for days
or weeks (the moment of corruption is really unpredictable). The next
thing is that I am accessing the DB with Delphi and IBX components
(the interaction is not really visible to me in every situation).

AFAIK the problem was that FB allows one to delete a record from
a dataset while accessing it within the same transaction. Is this right?

If it helps I can send a zipped db containing the corrupt table/index
(the size is about 3MB).
