Hi,

I developed a program using Delphi and I'm accessing a database of
4Gb. My program can access the database without any problem except
that, for an unknown reason, sometimes it is very slow and my program
seam to stop responding.

So, I thought that the database could be damaged or needed to be
defragmented. So, I decided to do a backup/restore using gbak.
However, when I try to backup the database, the gbak process never
end. I alo tried the gfix utility with the same problem. It can run
for hours without finishing. Usually, when I backup this database, it
tkes only 10 to 15 minutes.

So, is it mean that the database is corrupt?

What is strange is that I can access this database using my program.

Thanks for any help.
