Well, possibly... But I am fairly sure that this is what caused it
(there really were no other factors). Perhaps it was just a bit of bad
luck. However, personnaly, I would expect it to be corrupted. What if
it's in the middle of writing a record to disk, and it suddenly gets cut
of, with only part of the record written? Wouldn't that cause it to get
corrupted? (On the other hand, you might be right, as I can't pretend to
understand the internal workings of FireBird very well!).
