Public bug reported:

Information zzelle in conversation with njohnston

An overload is caused first by some neutron-servers crashed, secondly by
every l3-agent trying to perform a "full" process_services_sync. When we
restarted every crashed neutron-servers and purge neutron queues, we
restarted crashed neutron-servers rpc workers are still overloaded
because of full syncs.

About 60 L3Agents, with one router per L3Agent.

Key question: typically i don't understand why in full sync a l3-agents
request tenants with FWs intead of requesting its tenants with FW ?
