Bug Description
In nova.conf, when configured for HA by setting the memcached_servers parameter to several memcached servers in the nova API cluster, e.g.:
memcached_
If there are memcached servers on this list that are down, the time it takes to complete Nova API requests increases from < 1 second to 3-6 seconds.
It seems to me that Nova should protect itself from such performance degradation in an HA scenario.
