Our systems all have loopstats and peerstats logging enabled. I have

said, I might just not know what to look for in the logs.

        Look at the status word in peerstats; if the high bit is 
set, that's your huckleberry.

Correct, I was hoping to determine which peer it was so I can reach
out to them to make sure this doesn't bleed in to the pool at the end
of the year. I was also more-or-less curious how wide-spread of an
issue this was, but I'm starting to think I may have been the only
person to catch it in the act. :)

        You might want to upgrade to current 4.2.7 development code,
wherein a majority rule is used to qualify the leap indicator.
