"average 3" are accepted (while "minpoll 2" or "average nan" shout the
By default sysstats shows no rate exceeded, with or without "average 3".
Rate exceeded start to appear when adding restrict limited without
With restrict kod on the server, after some time the client logs "no
servers reachable" and doesn't poll anymore (but the refid stays "DCF",
no "RATE" or whatever). No problem with "average 3".
