Subject: [Openstack] Problem with dnsmasq - DHCPDISCOVER no address available
Hi All,
I have installed Grizzly with quantum and OVS-plugin. I'm using dnsmasq and
never had any problems with it until now. Dnsmasq is working fine in most of
the cases. But lately there were a few reports that dnsmasq is not working
entirely reliable. Sometimes dnsmasq claims that no address is available for
the specific mac-address, while other clients are still receiving their
addresses fine.
Details:
Used dnsmasq version is 2.59. The issue was recognized on Ubuntu 12.04 LTS.
Logs:

What could be the problem? Have you seen similar behavior? If yes, how did you
fix this?
