Thank you for looking into this; it's the first concrete information I've
had on an issue that has affected several people. Knowing the path is useful,
and also the confirmation that the daemon process is involved.

Your initial workaround should be to periodically restart the daemon.
If you have any info on the rate of growth, this would also help.
From the path, I'm guessing it'll be one per hour.
