Over the last 2 weeks, my mythbackend process grew from 30M to over
300M. Nothing new there, it's been reported before. What's really
annoying though, was that when I restarted it, I got back over 80Gb of
free space. That means that at least 40 deleted or expired programs
were being held open by the process. Now, near as I can tell, the
autoexpire code never opens any files, the leak must be somewhere
else.

Here's a sample of the expire related log messages
