The reason for this is twofold:
- It may relieve contention on DB access while
both servers and l3 agents are busy setting up
and syncing routers down respectively.
- It prevents accidental placement of namespaces
during the L3 sync_routers process, as auto
scheduling without taking into account the state
of the L3 agents, as well as the state of the
routers being processed, may overrule the placement
decision made during router operations.
