Romas, great question.
Looking back at the sequence of events, it does appear that the DNS
configuration was such that the primary was trying to ship logs to itself
for about 5 minutes after the last switchover. However, after that was
corrected, the configuration ran without a hitch until the standby was
restarted a few weeks later.
