Hi all
If I send local udp packets to vpp(17.02, the dst ip is local, but there is
no upper layer processing ) continuely, then vpp goes down like this.
If I change the next node of "ip4-udp-lookup" from "ip4-icmp-error" to
"error_drop", then everything is ok.
I'm wondering whether there is a bug, any clue here?
