Public bug reported:

When subnets or security group ports quantity reach 2000+, the ovs-agent will take more than 15-40 mins+ to restart.
During this restart time, the ovs will not process any port, aka VM booting on this host will not get the L2 flows established.
This is a subproblem of bug #1813703, for more information, please see the summary:
