Sebastian Lohff f9f6ae9c98 Limit max ports per rpc for dhcp_ready_on_ports() The Neutron dhcp agents reports all ready ports to the Neutron server via the dhcp_ready_on_ports() rpc call. When the dhcp agent gets ports ready faster than the server can process them the amount of ports per rpc call can grow so high (e.g. 10000 Ports) that the neutron server never has a chance of processing the request before the rpc timeout kills the request, leading to the dhcp agent sending the request again, resulting in an endless loop of dhcp_ready_on_ports() calls. This happens especially on agent startup. To mitigate this problems we now limit the number of ports sent per dhcp_ready_on_ports() call.

The Neutron dhcp agents reports all ready ports to the Neutron
server via the dhcp_ready_on_ports() rpc call. When the dhcp agent
gets ports ready faster than the server can process them the amount
of ports per rpc call can grow so high (e.g. 10000 Ports) that the
neutron server never has a chance of processing the request before
the rpc timeout kills the request, leading to the dhcp agent
sending the request again, resulting in an endless loop of
dhcp_ready_on_ports() calls. This happens especially on agent startup.

To mitigate this problems we now limit the number of ports sent
per dhcp_ready_on_ports() call.
