Comment (by jreed):

 I also see this sometimes... notice two scenarios below:

 {{{

 [b10-auth] DNSServices created.
 [bind10] Starting b10-xfrout

 }}}

 Not sure why above shows the set listen addresses twice. This takes
 b10-auth to 100% cpu.

 But I also have:

 {{{

 }}}

 Problem: it falls back to default listen addresses and ports. That is
 broken.

 I put into same ticket for now as I believe is related:

 But now it doesn't use high CPU.
