My router fell off the internet. When I got home, I found a few hundred
of these traces in the logs, and it refusing to route packets.
Oddly, it only prints a stack trace, and no clue as to why it printed that
trace.
There was also nothing in the log prior to this that indicates how it got that
B taint flag.
