I have similar problem, I use only one connection in single thread. It
is depend on database size and used function. I trying locate this problem,
but I don't have solution in this moment. I mean that problem is some bug
in gds32.dll and I want recompile this lib in debug for better monitoring,
but I don't know how it do. Can some body help me with compile gds32.dll?

With Regards Zdenek Kotala
