[NETVIRT-1353] NPE at updateVpnInterfacesForUnProcessAdjancencies

Tue, 3 Jul 2018 12:01:44 +0000

In an ODL 3 node cluster setup, when the following operations were performed we have seen couple of NPEs in the logs and observed that sometimes ping to FIP is failing.

Steps executed:
---------------
Start a VM, add FIP, kill compute on which the VM is running, delete the vm, create a new VM, attach the FIP to the VM.
