The last time it hung, 'netstat -n -i' showed: " Name Mtu Network Address Ipkts Ierrs Idrop Opkts Oerrs Coll em0 1500 <Link#5> 00:25:90:31:82:46 355482 10612864185945 0 291109 3032246910270 1516123455135 " That's from about 30 seconds after the interface 'stopped' - that number of ierrs/oerrs etc. - is just impossible for the traffic the machine handles, it looks like it's corrupt? Having dug around some more - I've now set: hw.em.enable_msix=0 After rebooting - the hang hasn't happened since - I'll leave it running like that for a while. If anyone can suggest anything to run when / if this happens again to track things down further - or any reason why it's doing it, that'd be great.. -Karl ps. Should have said before but the machine is running an amd64 kernel.
