We are still on I.B 6.0.

As I also wrote few days a go, we have something similar:

index page errors: 328
database page errors: 4923

We also didn't have these problems untill recently. Now we are doing
backup of the database 6 times per day, :). I wrote about this
problem few days a go, but only response I got was "go to firebird,
interbase is buggy". It seems to me that we sometimes get "automatic"
replys here. For me, even if I know IB6.0 has some limitations (or
bugs), I think if it worked ok for 5 years, pass on new version is
not "automatic solution" for some new problem.

Anyway, I would appreciate if you find solution for this if you can
send me private email with info what caused probelm to you.
