* *Resolution:* This suggests that cored was not running or is hung. Try "sudo killall cored", and if no process was killed, check also that there is not a /var/run/cored.pid file lying around. Try restarting cored in verbose mode: "sudo /usr/local/sbin cored -v" and if that works, restart it in daemon mode such as: "sudo /usr/local/sbin/cored -d". Check the log file in /var/log/cored.log if all else fails. * *Resolution:* This suggests that cored was not running or is hung.

* *Issue:* when starting multiple quagga routers, only some come up into operational state.
* *Resolution:* This is flakiness with the OpenVz version of CORE. I have noticed that sometimes the containers start without interface lo in an "UP" state, and that zebra sometimes does not start successfully. If you find a node in this state, here are some suggested resolution steps:
{{{
killall zebra ospfd ospf6d
ifconfig lo up
zebra -d
ospf -d
ospf6d -d
vtysh -b
