Hi,

I've started the es cluster on 2 EC2 instances (medium, 2 core, 3.75G memory) using Amazon Linux, and Using java TransportClient to connect to the cluster (See my other email for why I didn't using native client. Which has no answer yet)

when the cluster start everything is ok but when it running for couple of days or a week it sometimes freeze when I want to update the index. In my business logic we have some small frequently updates. After I restart the es cluster it went back ok again.

Can anyone give me some advice to avoid the problem? At lease it can keep running for a month without problem.

hey,

when you say it freezes, what is the exact sitiuation you are seeing. do  
you get an error or do you fail to execute searches, does something time  
out etc? What is the cluster health status at this point and can you  
reproduce the scenario?
