Sometimes I get this error..

internal gds software consistency check
Can't continue afer bugcheck..

or this error..

database file appears corrupt()
wrong page type..

When I check the database with gfix, it says nothing is wrong.
I can backup and restore...

And when I restart the application, everything works fine..

I have a mandrake linux server with firebird 6 RC1 installed, and
clients
use windows with the latest bde driver installed.

What's wrong?

thank you
