Hi,
I would guess (correct me if I am wrong) that you are using Exchange 2003 Sp2 Standard edition. I believe you have added the relevant registry entries to limit the size of your DB to 75GB.
This event is simply letting you know that you have put the limit in place and that should the size of the DB become the same as that of the limit, then the DB will dismount.
As such, this is not an error just a warning. It also lets you know that the current size is 21GB, so nothing to worry about yet a while.
Cheers
Nathan
