I guess my question is why did it withdraw the IP and then suddenly rejoin?
The mDNS package (multicastDNS) thinks you're disconnecting from the network and reconnecting again. If the rest of the your network services disappear for a short time as well, then you may have an intermittent cable problem. Try swapping out the cable and see if the problem goes away.
If the rest of your network services stay up while mDNS goes down, then it's just that one service. All I can think of in that regard is some kind of autoconfiguration process that is running periodically and it causes mDNS to shutdown and then come back up. I don't know what type of service it may be that does that, though. You could try Google'ing it and see what you get. Another (rather "overkill" technique) would be to turn on system accounting and the next time you see those messages in your log file check the accounting data and determine what was running during that time period.
Yet another technique (just as much overkill as the previous) would be to run
strace -f on the mDNS service (add the timestamp option to strace; probably
-t or
-T) and then you can see what's happening inside the application by comparing timestamps with the next occurrence that appears in the log.
Warning: the strace option will create a HUGE amount of data! Especially if it takes hours or days before the entry is repeated in the log file.
