Hello, I've searched through the group here and found a lot of information, but I am hoping someone could help me verify my configuration - as I have been running into many issues running ES. I have a very simple setup with a small number of documents and only one index (currently about 100 documents in the index). Over time, the search becomes unresponsive and ultimately hangs or crashes, and I haven't been able to pinpoint the exact reason because there are 20-30 different random debug/error messages in the logs. What I have for my elasticsearch.yml: node.local: true discovery.zen.ping.multicast: false threadpool.search.type: cached #network.bind\_host: _local_ #network.publish\_host: _non\_loopback_ #network.host: localhost The only thing I have set in my elasticsearch.conf: ES\_HEAP\_SIZE=8g I am running ES 1.4.2 on an Ubuntu VM (SSD, 14gb RAM, 2 CPU) out on Azure, I also have the Marvel plug-in installed, and latest JVM. The index size is about 1 megabyte (the marvel indexes are there too and larger - this is just the index I created and maintain). Using the NEST API through .NET for indexing, searching, and deleting. The reason i have the threadpool.search.type: cached setting is because the most recent error I was getting had to do with reaching a queue capacity limit of 1000. Restarting ES fixes it every time it hangs/crashes - but it only lasts a day or so then it crashes again. Any help would be appreciated. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

How much data overall do you have? If you are getting queue capacity limits then chances are you're overloading your instance.
