Hello John, Thanks for the response. > > Have you tried increasing kern.ipc.nmbclusters? Alternatively, have you > tried > restricting igb to only using 1 queue? It sounds like all your igb > interfaces > are allocating all of your mbuf clusters for their receive rings. > I found this very suggestion on several mailing list discussions [1] and set these values on Saturday. kern.ipc.nmbclusters="131072" hw.igb.num_queues="2" So far everything seems to back to normal, and netstat -m shows plenty of headroom now.
The problem cropped up after running several months on 9.0-RELEASE when I brought up another interface. Disabling the new interface didn't restore normal operation, however. I also tried 8.3-RELEASE but the problem was worse on it.
