Public bug reported:

In our work on upgrading from Queens to Rocky, we have stumbled upon
some weird behaviour in neutron-l3-agent. After "a while" (usually
~days), the l3-agent will simply stop processing router updates. In the
debug log, we see:

Got routers updated notification :[u'1dea9d84-e5ec-44be-b37f-
7f9070dd159e'] routers_updated /usr/lib/python2.7/dist-
packages/neutron/agent/l3/agent.py:446

But then nothing happens after that. We're testing this with adding and
removing a floating IP.

The problem is that we really have noe clue what happens, other than the
observed symptoms, so we can't really provide a way to reproduce this..

neutron-l3-agent     2:13.0.4-0ubuntu1~cloud0
openvswitch-switch   2.10.0-0ubuntu2~cloud0

Ubuntu 18.04 LTS, running the 4.15.0-51-generic kernel
