Please look for this script in correponding folder and check file content.

SQL Server 2000 often build bad scripts if article filter has complex condition

and article shapshoot is reinitialized...

Sorry, try

ALTER DATABASE DBName

MODIFY FILE (name=DBName_Log, size=IncreasedSizeInMB)

and then

DBCC SHRINKFILE (2, DesiredSizeInMB)

Try ALTER DATABASE MODIFY FILE (name=_Log, size=) and then

May be you need to check execution plans. I suppose that for fast example it was build better execution plan because SQL Server has real values of parameters during building...
