Hi again, I have a doubt about how things work in ElasticSearch : I've shut down a node for which a gateway configuration was set. However, when shutting down the gateway, I saw the following messages in the log. For me "warn" means that it is not important, although "outofmemory" generally means "failure" for me. Is it that ElasticSearch will try another method (no memory mapped files) for storing the index in that case, or will I loose part of my index ?

In the upcoming 0.9 I removed completely the native transfer from elasticsearch as its so buggy in Java. In 0.8 you can disable it by setting `index.gateway.fs.native_copy` to `false`. -shay.banon On Thu, Jul 1, 2010 at 1:16 PM, Cédric [cedric.champeau@gmail.com](mailto:cedric.champeau@gmail.com) wrote: > Hi again, > > I have a doubt about how things work in Elasticsearch : I've shut down > a node for which a gateway configuration was set.
