Dear Jason,

thanks for the time you spend for me. I will try
to check the things you suggested!

I think, the problem is only one application, which opens
al large living dataset. The application is starting at morning
by the user, opens the dataset for browsing, searching
and editing. And the transaction is still open whole time.

But, when i close the transaction, reload takes time and the
users will be discontented...

Now i will start searching the FAQ.

Thanks again!
