Your second two links do not work.

Can you add another node, or close some old indexes?

Hi,everyone
I'm new to es ,i got a probem with es and tried a lot but still don't
know how to change the situation ,so i would be gratitude if you can
give me some advice about better performance of es searching

I build a es cluster with 2 nodes, in order to analyse logs for develop engineers
,like some 5XX,4XX status and so on. It's running good ,but when i open
kibana (only one user) which will do some queries to es, then the 2 servers
will perform high cpu load. when i close kibana ,cpu load will be nomal
again.

there are some details about the problem below:

My server basic information:

RAM: 48G
cpu cores :4
centos 6.5 kernel version 3.8.13

jdk : jdk1.7.0_67
es version : 1.1.1

the work i have done:

when i google the problem, i got some possible solution

1.the leap-second
since my kernel is 3.8.13, so the kernel had solved this problem

I'm sorry for my bad english.
