<div dir="ltr"><div>If there are any errors on the agent connecting to the message bus or retrieving messages, an exception will be thrown in the main rpc_loop, which will be caught and a sync flag will be set to true, which will trigger the sync on the next loop.</div><div><br></div><div>However, I briefly looked through the L2 agent code and didn't see a periodic task to resync the port information to protect from a neutron server that failed to send a notification because it crashed or lost its amqp connection. The L3 agent has a period sync routers task that helps in this regard. Maybe another neutron developer more familiar with the L2 agent can chime in here if I'm missing anything.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 12, 2015 at 6:19 AM, Leo Y <span dir="ltr"><<a href="mailto:minherz@gmail.com" target="_blank">minherz@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">What does it mean under "if that notification is lost, the agent will eventually resynchronize"?
