I had similar results when the update scripts for either ClamAV or F-Prot
(which I use)were unable to reach their respective sites.  When those
scripts run MailScanner is stopped using a lockfile.  If they don't exit
properly mail continues to be received in in.queue but MailScanner isn't
available to process the mail and move it out for delivery.

I modified my scripts with timeouts to prevent this.  I also noticed that
I had a series of timeouts with F-Prot the other day when they were having
problems with their site.
