Question : document not saved

We have been using MOSS for the last year and upgraded to Office 2007 from Office 2003 in July 2007. In the last two days nobody can save to the MOSS portal word , excel or PDF documnents. I have checked the content database using SQL manager and it is reporting no issues. I have checked disk space and there 50gig free on the data drive and 12 gig free on the C drive. Office 2007 has service pack SP1. The SQL server is running 5 gig of memory with 4 gig being used. CPU usage is negligble. I have checked the MSDN sites and Googled the error messages with no luck. The next stop is Microsoft which takes a while. Any ideas would be great.

Answer : document not saved

Found the problem. There was a limit on the size of the log file in the database. It would not store anything because it could not be logged.
