Description

Don't really know what more to say other than what was in the syslog:

I suppose I could add that this was on a D-Link DIR-615 rev. C1. The same one referenced in ticket #19640. It's actually doing absolutely nothing at the moment due to the problem described in that other ticket, so the above happened on an otherwise idle router.
