Comment 1 for bug 1468839

In the logs I see

```
2015-06-24T22:41:01.537318+00:00 debug: Memcached pool 90129936, thread 140052079146752: Marked host 192.168.0.10:11211 dead until 1435185691.53

same for the second token:
```
2015-06-24T22:31:07.226938+00:00 debug: Memcached pool 61707152, thread 140200754067200: Marked host 192.168.0.10:11211 dead until 1435185097.09

```
which means that memcache host became dead there. Keystone in 6.1 requires some seconds to failover.

Were the tests destructive?
