It seems, that this message will be issued when a number of retransmits for a given destination becomes high, forcing the deletion of the route in hoope for a better one. Anyway, this does not hurt you in no way. It is possible, that some destination host has a bad connectivity with high loosage rate, causing this message to be generated. > As for maxusers, I have it set to 30.
