Hi Guys!
If your logs are growing take a look to the DBCC SHRINK way...
msdn.microsoft.com/.../ms189493.aspx
It's works like a charms in SQL Server since 2005 ...
The file name should be found in the SQL database properties in the file section
USE ksubcribers;
GO
DBCC SHRINKFILE (ksubscribers_dat_log, 1);
GO
