Some of our servers have 4/6 interfaces connected to the switches and they fail to submit LLDP information. After some lecture of the code I found a comment suggesting that an empty list returned from select means a timeout on all interfaces (https://github.com/openstack/ironic-python-agent/blob/d0092633498c6611f5419d5b832042d57d344c8f/ironic_python_agent/netutils.py#L175). However, select's documentation claims that "When the time-out is reached without a file descriptor becoming ready, three empty lists are returned." |
