OK, you made me curious enough to go and take a peek at the code. This
message originates from module ".../netinet/in_rmx.c" routine
Essentially, it appears to be trying to flush the routing cache of stale
entries (ie. those that have been there for 'rtq_reallyold' seconds but
havn't been used!).

Nothing... It's simply an advisory that the value of rtq_reallyold is
being reduced by 1/3 of it's current value. It starts at 60 * 60 (3600
seconds) so the first reduction reduces it to 2400 seconds and the next
to 1600, etc. I believe that it keeps doing this until it reaches the
minimum value which is 10 seconds. The idea is to keep the routing
cache to 128 entries or less. If no entries are being flushed, then the
value of rtq_reallyold keeps getting reduced to try and force the issue!

My advise is... "DON'T PANIC!" I've been ignoring this message for
several years now and nothing untoward has happened to my routing
tables. Now that I've read the code, I can sleep even easier at night.
