FreeBSD 11.1 netif restart hangs

I am using FreeBSD on Azure VM and have updated OS as per available instructions. Upgrade goes well and now I have
Code:
# uname -a
FreeBSD my-vm 11.1-RELEASE-p4 FreeBSD 11.1-RELEASE-p4 #0:
As soon as I try to restart network service it gets hang and do not come back until I restart VM
To restart network service I have tried these command individually and in combination with && as well
service netif restart

or
service netif restart && service routing restart

After rebooting VM following is appearing in debug.log

Code:
 ifa_maintain_loopback_route: deletion failed for interface hn0
Please suggest if there is any fix

Thanks
