I could be wrong but I would think that if the log is stating that the
entry already exsists you would need to clear any dhclient data associated
with that entry. You may want to try running the tail as you restart the
service to see if it will point to the specific issue. If a dhclient entry
is there it will tell you the exact problem. Also, on the number of logs.
They would grow as dhclient requests increase. you may want to look at the
TTL in your conf file to see if the TTL is so low that the renewals are
filling your logs up. Hope this helps. If not let me know what you found is
