Is this a serious problem ? in_rtqtimo is the routine that periodically cleans the IP per-host information cache (part of the routing table). If, in the process of cleaning, it notices that there are ``too many'' entries in the cache, it cranks down the maximum lifetime of a cache entry and re-expires. The parameters are all tunable, in the net.inet.ip branch of the MIB: net.inet.ip.rtexpire = 3600 # current max lifetime net.inet.ip.rtminexpire = 10 # minimum max lifetime net.inet.ip.rtmaxcache = 128 # how many is ``too many'' -GAWollman -- Garrett A.
