Maru Newby 2014-03-12 04:16:28 UTC Doc Text Cause: The Neutron service previously fails to process agent heartbeats in a timely fashion when overloaded, causing agents to be considered 'down'. Since the service was only sending network changes to the DHCP Agent if it was 'up', an overloaded service would fail to send notifications to the agent.

Consequence: The DHCP Agent would be unable to serve requests for ports for which it was not notified.

Fix: The Neutron service has been updated to always send dhcp notifications even if the target agents are considered 'down'. Additionally, an error will appear in the logs if a dhcp notification cannot be sent because no dhcp agents are available.

Result: The DHCP Agent will always be notified of network changes and be able to eventually respond to DHCP requests for configured ports.

Since the service was only sending network changes to the DHCP Agent if it was 'up', an overloaded service would fail to send notifications to the agent.

Result: The DHCP Agent will always be notified of network changes and be able to eventually respond to DHCP requests for configured ports. 		Networking previously failed to process agent heartbeats in a timely fashion when overloaded, causing agents to be considered in a 'down' state. Since Networking was only sending network changes to the DHCP Agent if it was 'up', an overloaded service would fail to send notifications to the agent.
As a result, the DHCP agent would be unable to serve requests for ports for which it was not notified.
With this fix, Networking has been updated to always send DHCP notifications even if the target agent is considered 'down'. In addition, an error message will be logged if a DHCP notification cannot be sent due to unavailable DHCP agents. DHCP agents will now always be notified of network changes, and will be able to eventually respond to DHCP requests for configured ports.
