Do you see memory allocation errors in netstat -m? Specifically this line: 0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) If so, it may be that the IPoIB layer has an mbuf leak. The rest of netstat - m might be useful here as you can see if any of the zones are full. -- John Baldwin _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
