Interesting bugs, thank's. But I'm not sure they concern nova-consoleauth in my opinion. 

Is somebody here still working on Folsom ? I'm curious if nova-consoleauth is working in active / active too.

Keep in mind there are a couple memcached bugs that were recently resolved in 2013.1.1:

Hi, 


We are running : 


    * 2 memcached servers on dedicated nodes 
    * 2 nova-consoleauth with memcached_servers flag in nova.conf (don't forget to install python-memcache on nova-consoleauth nodes) 
    * 2 nova-html5proxy in load balancing with HAproxy in front-end. 
It works fine. 


Cheers ! 


Emilien

Great, thank guys!!, Should i run one memcache server??? instead of running many of them, one in every compute node, using the configuration John Dewey says.

If you run multiple consoleauths they need to talk to the same memcached server.

Hi guys, on friday i was trying to reach my vms through novnc proxy and i ran into some kind of odd behaviour. One every two attempts were successfull so we started watching logs. after a couple of hours stopping and starting services we realized that this strange behaviour was due to we had two nova-consoleauth instances running, one per compute node. We stopped one of the instances a everything started to work just fine, even both novncproxies. 
I found this https://bugs.launchpad.net/nova/+bug/989337 but it's suppossed to be fixed in folsom, and i'm running grizzly. 

Should i run just one instance of nova-consoleauth?
