Hi, Having a strange issue when trying to get a document by id, i.e GET to [http://localhost:9200/index/type/](http://localhost:9200/index/type/) Sometimes Elasticsearch returns a HTTP 200 but a totally empty response. The other strange thing is that the content-type of the response is text/plain; charset=UTF-8 rather than the expected JSON. This is causing major problems because when it occurs when I'm trying to update a document my client library thinks there is no data for the document and just indexes the document with purely the updated data, causing data loss. Anyone got any ideas? Thanks. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

\_source is enabled, if I fetch other documents, or fetch one of the documents after update & data loss, the \_source is present. The response I'm occasionally seeing is completely blank (no json or anything), just an empty string.

Not tried it on a clean index but found a way around the problem. If I tell my client library to not use persistent (i.e keep alive) connections then this issue goes away.
