I have the following error:

```auto
{"error":{"root_cause":[{"type":"timeout_exception","reason":"Failed to acknowledge mapping update within [30s]"}],"type":"timeout_exception","reason":"Failed to acknowledge mapping update within [30s]"},"status":500}

```

This happens on production while importing a folder of xml documents with sizes of 500kb-14mb. Each file is processed separately and there are no more than 90 files in a folder. Locally I am able to import the same data (after increasing jvm.options  
Xms1g to 2g  
Xmx1g to 2g)  
without ever getting the error.  
As far as I understood there is no timeout option in elastic so i do not know if i can do anything on that part. Any ideas what causes it or how can i simulate it locally so I can continute debugging from there?
