Imagine

Imagine you create a incremental deployment job that runs every 15min. Imagine after a while something is going wrong...you look and the sql server and it has 0 bytes free :o

You start browsing the files and the wss_content_log has 10Gb... wtf?!?

change the recovery model to simple and then use this sql to trunk the db

BACKUP LOG wss_content WITH TRUNCATE_ONLY
DBCC SHRINKFILE(wss_content_log,2)

this worked out for me hope it helps, tks ricardo :D
