Can you verify that you don't have duplicate MAC addresses on different NICs? Sounds like a switch's ARP tables might be getting messed up. Haven't seen that on x86, only on SPARC with local-mac-address?=false > - Z IPs sporadicly send out ARP requests for their own MAC. > > - I can ping G from A, but don't see any packets in snoop (either -d e1000g0, > which should be the right NIC or any other, where it would be wrong to see > them) Unless you are using exclusive IP Instances, pings between zones on a system will not leave the system (neither global to non-global nor non-global to global).
