Hi,

I am running elasticsearch 1.4.4 with java 1.8.0.25 on windows machine . i  
have assigned 2 Gb heap memory  
java.exe taking almost 70 per cpu ?  
everything else is working fine  
Can somebody please give right direction to diagnose what is causing this  
fluctuation

Thanks

What is wrong ?

I mean that if you are doing indexing for example, that's fine if your CPU is used.  
But may be you are running out of memory and GC is running all the time ?

Hard to say without any details / logs...
