[Bug 1431191] [NEW] dhcp-agent running error：“RTNETLINK answers: Invalid argument”

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

The dhcp-agent running error In my openstack system. Two ports in the
network, one is active status , another is build status.

Base config options:
      "dhcp_delete_namespaces = True"   in /etc/neutron/dhcp_agent.ini
      "dhcp_agents_per_network = 2" in /etc/neutron/neutron.conf

Neutron informaton :
       icehouse       release = "1.el6"    version = "2014.1.2"

OS is CentOS 6.5

I  found some log in the dhcp-agent.log file, such as:
