We were running out of disk space on a Small Business Server 2008, giving us Exchange back pressure problems halting email delivery. The SBS2008 Best Practices Analyzer (BPA) reports that 'The log file for the Windows SharePoint Services configuration database is getting large'. For information about how to reduce the size of the log file, see the Knowledge Base at http://go.microsoft.com/fwlink/?LinkId=159745
Unfortunately that link is now dead, 'This page doesn't exist' and searching MS fails to show the relevant info to fix the problem.
The Microsoft FixIt however is still available for an automatic fix, use this link

Gave me an extra 8GB of disk space within seconds.
