Hi, Here is something worth sharing, I think. For Logsene [http://sematext.com/logsene/](http://sematext.com/logsene/), We've been trying out EC2 R3 instances (specifically r3.large) with Elasticsearch (1.1.x and 1.3.x including 1.3.2) with the latest Java 7 update 67. We tried this on Ubuntu 14.04 AMI, as well as Amazon Linux AMI. In all cases we see Elasticsearch (or the JVM?) periodically "freezing" for minutes at a time. Here is a graph that shows this: [https://apps.sematext.com/spm-reports/s/kOn7sFUCe2](https://apps.sematext.com/spm-reports/s/kOn7sFUCe2) -- uncheck all checkboxes except the one on the right -- "total opened HTTP conns (total\_opened)'" and you will see the pauses on 3-4 servers happening. We'll move off of R3s, but wanted to share this in case anyone else runs into the same problem. We don't have this problem on instances of other types we are running. ## Otis Monitoring \* Alerting \* Anomaly Detection \* Centralized Log Management Solr & Elasticsearch Support \* [http://sematext.com/](http://sematext.com/) -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

We are actively using the r3 series in EC2 and have not experienced any issues. We are also using Java 7u67 but we are using Ubuntu 12.04 exclusively. We have tested with ES 1.1.1 and 1.3.2 and have not run into any issues. We are predominantly using the r3.2xls but I think we have used some r3.xls and r3.larges. Are you doing anything special with networking? Drivers? EBS optimized? Thanks, Chris -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Otis, are you using CMS GC or G1GC?

That is a good question. We noticed long GC pause times before we switched over to G1GC. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
