      [root@localhost vpplb]# vppctl show interface
      Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count
      GigabitEthernet2/3/0 1 down 9000/0/0/0
      GigabitEthernet2/9/0 2 down 9000/0/0/0
      GigabitEthernet2/a/0 3 down 9000/0/0/0
      local0 0 down 0/0/0/0

      The 2/3/0 and 2/9/0 are connected to different subnet, when I enable two dhcp client, vpp crashed.

      vppctl set interface state GigabitEthernet2/3/0 up
      vppctl set interface state GigabitEthernet2/9/0 up
      vppctl set dhcp client intfc GigabitEthernet2/3/0
      vppctl set dhcp client intfc GigabitEthernet2/9/0

      Here is the calling stack from gdb
