Ok - Status as of now.

Last nigth I disabled the sweep function and had it done manually each
nigth (When the are no connections).

The last 2 days (25 and 26) there has only been some 10 - 15 connections.
All that time, the gab between OAT and NT never got bigger than 40!

Today is the first "real" work day.
And at this point the gab is some 80.000.
But they run smothly.

After I read what Ann said about transactions I understand why the OAT
isn't moving along as I thougth it would.
I will have to look into what kind of operations the customers a
doing. Because they do someting to make the gab grow more than expected...


Now I will monitor the DB for some time, to see if disabling the sweep
helpes.

Thx to all so far.
