I was the person with issues with 10's of l3-agents not working properly on Liberty. With about 100 l3-agents we had issues with them just falling over without anything going on. We moved to 20 l3-agents and with that config we've had good luck unless you restart all of them at the same time. My understanding is that in Liberty there is a single thread per neutrons-server (we run 3) that handles agent traffic and that this was supposed to be fixed in Mitaka and newer, but I haven't seen that confirmed.
The patch that implemented separate workers for agent state reports is: https://review.openstack.org/#/c/233605/ and was indeed included in Mitaka+.
