I'm not exactly sure what happened but I may have caught the system in
the act of trying to run away. Below is the last two lines from the
peers log for one of the peers and below that is the output of ntpq
showing what happened to that peer immediately after. Note the offset.
This somewhat matches what I had been seeing previously where my
system would be reporting sane numbers and then very suddenly go haywire.

After a couple minutes things went back to normal as if nothing had
happened:

It's the fist time that I've actually been able to see this happen while
staring at the monitor. I'm not certain but I suspect that the last few
times this happened where the system did run away the peer that
experienced the strange behavior happened to also be the selected system
peer. I can't explain the behavior though because everything looks fine
on my system otherwise and the remote server also seems to be fine given
that its offset was normal just before the update.
