After a few hours of operation, ntp loses the ability to send packets.
sendto() returns -EAGAIN to everything, including the 24-byte UDP packet
that is a response to ntpq.

...

Killing and restarting ntpd gets it running again for a few hours.
Here's after about two hours of successful operation.  (I'll try to
remember to run slabinfo before killing ntpd next time.)

ntpd.  Sounds like pps leaking to me.

Can anyone offer some diagnosis advice?
