I've had ElasticSearch crash twice on my production servers in the last 24 hours. This has me very concerned; I can't afford to have this kind of instability. I'd really appreciate any insight anyone can provide. [[EDIT]] 4 crashes now in 3 days. I'm running v0.20.5 on EC2 with 2 nodes in my cluster. I'm running with 4GB of RAM allocated to ES and 64k max open files. I'm not seeing anything interesting in the log files, at least to my eyes. There are a fair number of "failed to execute search request" errors, but this is because I've exposed the search portion of my API, and others are bound to accidentally mis-use the search queries (I have not exposed anything but searching a single index). Other than that, I don't see anything else in the logs. Here's the full log file: [http://streamified.com/downloads/streamified.txt](http://streamified.com/downloads/streamified.txt) ---

What do you mean by crash? Does elasticsearch process just disappear? Which version of java are you using?

Hm, yes, the process "just disappears." I guess I assumed that meant a crash, but I don't know how to verify. Java: java version "1.6.0\_31" Java(TM) SE Runtime Environment (build 1.6.0\_31-b04) Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode) ---

When java crashes it sometimes leaves behind java\_pid.hprof files where is pid of the java process that crashed. With elasticsearch it typically happens when elasticsearch runs on an old versions of java. So, I would recommend upgrading to the latest version of java 7 or at least the latest version of java 6.
