Hello,

I have a single node cluster. Recently I've updated to the latest version of ELK (6.2.3).

I'm not sure if my problem is related to updating to a newer version or it's just a coincidence, but I've noticed that my scroll requests started constantly failing on 1 shard out all of all available.

My python script fails with the following message:

```
  File "/usr/local/lib/python2.7/dist-packages/elasticsearch/helpers/ __init__.py", line 394, in scan
    (resp['_shards']['successful'], resp['_shards']['total'])
elasticsearch.helpers.ScanError: Scroll request has only succeeded on 555 shards out of 556.

```

Corresponding elasticsearch logs:

```
