Hello, Stef. You wrote 20 =E0=E2=E3=F3=F1=F2=E0 2009 =E3., 08:20:17: > I'm having a problem on an old FreeBSD 6.0 box, that's a wireless > router, been running steadily for years. > A short while ago (perhaps due to a change in traffic), every few hours, > the wireless interface becomes unresponsive, and I started seeing > thousands of lines like this in: > ath0: ath_rx_proc: no mbuf! > The mbufs are in fact all used up. 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 <lev@serebryakov.spb.ru>
