freshclam.log and clamav.log suddenly empty...

My mail server appears to be running fine, and the databases are updating...but...it appears the clamav and freshclam logs are suddenly empty. No config changes happened on the server, they just stopped logging and haven't restarted. One other odd thing: In Server Admin, under the "Update the virus databases X times per day" it shows "Last update: Not available."

For the heck of it, I decided to temporarily rename the log files to see if I could get fresh versions to generate. Bad things happened...so I moved them back. Suddenly, the virus update log started to work again, but the clamav did not; it is still empty.

Any ideas on what is happening?
