    duplicated packets seen in snoop. severe network performance degradation


      Hi !,


      we are seeing a strange problem in some machines with Solaris 5.10U10 x86_64. From time to time we see a huge network performance degradation. One curious thing about that is when taking some snoop network traces we see that the Solaris machine is duplicating packets over and over (same packet, not retransmissions). When taking traces in the switch, we only see one packet, but the snoop traces show lots of outgoing multiplied packets.


      Have you ever seen such a behavior?


      Do you know if snoop code sniffs the packets after or before the nic driver?




      All the outgoing packets are multiplied. Even with a simple ping we see duplicated/multiplied packets ,


      Thanks so much,
