We're running into issues when we restart ElasticSearch.  
We're using a default-mapping.json file with dynamic\_templates.

The first time the server is restarted, we see that the  
dynamic\_templates are "doubled", the second time we restart the server  
we see the templated trippeled etc.

How do we prevent this when we're using a default-mapping.json file?

Heya, yea, its a bug, opened an issue:  
[Mapping: default mapping with dynamic templates can cause them to double on each restart · Issue #1964 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/1964).
