Public bug reported: While looking at another issue, I noticed this error in the l3-agent log:

I think in this case the pid file has simply not been written yet and the process is still spawning, so we should print a warning to that effect. That way if the admin does see an issue with that router there is something to indicate why. ** Affects: neutron Importance: Low Assignee: Brian Haley (brian-haley) Status: In Progress ** Tags: l3-ha -- You received this bug notification because you are a member of Yahoo!
