bug 1542009 was fixed for the crash happening in InterfaceKSyncEntry::DeleteMsg
Now, agent is again crashing nterfaceKSyncEntry::AddMsg Please fix this

Steps

admin nodeh3 left_vm ubuntu 1.1.1.249 m1.small Active None Running 1 hour, 22 minutes
admin nodeh3 contrail_svm analyzer 1.1.1.250 1.1.1.252 m1.medium Active None Running 1 hour, 23 minutes
admin nodeh3 right_vm ubuntu 1.1.1.251

1)Port mirroring enabled on left vm

2) Two more VMs (as shown below) both on different CNs, starting ping 10.1.1.4 from 10.1.1.6 , restart ing vrouter on nodeh3 is causing vrouter to crash every time

admin nodea21 vm-4ubuntu 10.1.1.4 m1.small Active

admin nodeh3 vm-3 ubuntu 10.1.1.6 m1.small Active
