Hi, ifconfig flags: <UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER>
ping doesn't work snoop says that igb1 (broken interface) is sending out ARP packets (who is) and SYN / RST packets. No other communication from the outside. Yes, I am running link-based failure detection. The idea is to enable probe detection in the future but not right now. It could be tricky to disable all interfaces to use dtrace probes however I am able to create live dump of the system.
