What this means is that the kernel IP per-host cache timeout code
noticed that you had a lot of unreferenced routes piling up in the
cache, and it has taken steps to reduce the expiration time in hopes
of reducing this to a number it considers reasonable.

The following sysctl(8) parameters control the operation of this
function:

net.inet.ip.rtexpire = 3600	# the expiration time
net.inet.ip.rtminexpire = 10	# the minimum expiration time
net.inet.ip.rtmaxcache = 128	# how many is ``too many''
