Hi Han,

This seems to cause an assertion failure in ovn-controller compiled with
today's OVS/OVN master branches. I'm not completely sure about the steps
to reproduce because I was testing some other ovn-k8s related things but
I did get a core dump and the NB/DB/conf DBs.

I opened a RedHat BZ [0] (more for my tracking than anything else) and I
shared there the OVS/OVN revisions and how to build the exact same image
that I was running when I hit the crash.

I'll try to investigate what's happening but you're probably more
familiar with the code so any hints would be great.
