I have a StatefulSet in Openshift that keeps restarting, but only on a single node. I don't see anything in PODs logs. In `/var/log/message`s I see only messages that container is restarting, volume is unmounted etc and some more cryptic `'error: Container is already stopped'` and `'cleanup: failed to unmount secrets: invalid argument'`.

However, when I look and Yaml for StatefulSet I see the following:

```
status:
  collisionCount: 1
  currentReplicas: 1

```

I suppose this is what is the real cause.  

But how can I find out what has generated that collision?
