Empty ULS (12 Hive) Logs

I was looking into turning on the Usage Analysis Processing and poked into the 12 hive LOGS folder as that is where Usage Analysis log files are stored. I noticed that the ULS log files (which are normally huge, since SharePoint logs every thing it does), were all 0kb. I thought I had this problem before but could not find any answers, so I started searching. I finally found a blog that talked about empty MOSS logs and it jogged my memory that one of the things that will fix this is to restart the Timer job service.



So I went into the services and restarted the Windows SharePoint Services Tracing and Windows SharePoint Services Timer services and the minute they were reset, the logs started filling up.



I have not found a reason for them to stop logging yet, but I am still looking.
