Is this something I need to be concerned about? Disclaimer: The following is how i understood it. I might be incorrect. Background: For each network route that applies to a particular destination, this route will be cloned into a (temporary) host route for this destination host. This is done for several reasons, one of them being efficiency (host routes are very efficient). You can see all these cloned routes with ``netstat -ra''. These cloned routes expire after some certain amount of time. The expiration parameters can be controlled by some sysctl(8) variables (net.inet.ip.rt*). Since the cloned routes eat up memory, a machine that does a lot of routing might use too much memory for keeping potentially stale cloned routes, and so the system protects itself by adjusting the expiration time. The syslog message is left as an indication of this happening, and perhaps as an indication to the operator that the machine is running slowly out of some buffer memory. However, short of adding more phyiscal RAM to the machine, please don't ask me for which parameter to tune. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
