Subject Firebird 1.0.2 Sweep Database

I have a database that is 1GB in size with approximately 3 million records (total) stored in several tables. I have taken the database offline and tried to do a sweep, but it ran for 8 hours and didn't finish. How long should it take? I am not getting any errors at all.

FYI, the PC is a PIII 1Ghz Dell...
