This is still happening with ntpsec-0.9.7+1104, albeit much less often
now (but I've removed iburst from the configuration files).  I just had
it happen while I was updating the rasPis.  Again, the symptom is that
there is a "rate_exceeded" event and the hpoll gets set to some high
value and never recovers from there even though the poll interval should
be fixed:

assoc=53276: conf, reach, sel_reject, 1 event, rate_exceeded
unreach=0 hmode=3 pmode=4 hpoll=10 ppoll=4 headway=7908 flash=4096 keyid=0

This was and is not happening with NTP classic.
