Comment (by naokikambe):

 IMO stats seemed to be working as we expected. When a auth instance is
 dead, stats loses all statistics which it has sent before. This behavior
 doesn't change whether the auth instance is single or multiple. As a
 result, the numbers which stats shows via bindctl may look decreased.

 In another case, if the counter in auth overflows and the number is reset,
 the same behavior might be seen. But I don't think the numbers reached the
 maximum yet. Because the counter value in auth seems to be defined as a
 "unsigned int":
 {{{
 src/lib/statistics/counter.h:    typedef unsigned int Value;
 }}}
