Hi Gerhardus, i'm using Delphi Clients (ibx) with Firebird Linux Server
too....
a lot of time ago i got some messases like yours when executing gbak from
crontab...
two things i had to implement:
a 'kick every body from database' event....
and before the delphi client try to log in it check if exists a lockfile
that i defined....
so my crontab looks like:

- put lockfile in place
- kick everybody
- gfix to validate the gdb
- gbak
- take of the lockfile

i think the problem was users trying to login while gbak is running...
what was causing a lot of validation errors....

that's it... wish this help you...
