I'm hoping that this will be a simple problem.

I have a database that is running in a FB1.0 environment quite
happily. As an experiment, I've installed FB1.5A4 onto a separate
machine and attempted a restore (using GBAK).

If I try to access the restored database I get a DEADLOCK error.

Can anyone tell me what is going on here and, more importantly, how
I fix it?

Thanks
