I allocate more via > kern.ipc.nmbclusters, and see the same behavior. Same problem here on 7.2-STABLE, but incresaing kern.ipc.nmbclusters to 65536 helps. It seems, that when traffic is reauuly huge, system with ath need a lot of mbufs. At night, when traffic is almost zero, netstat -m shows a lot of free mbufs and clusters, so it seems, that there is no mbuf leaks. --=20 // Black Lion AKA Lev Serebryakov
