I have a 3 node cluster. Whenever there are too much traffic, the process CPU percent shoots upto 300%  
This causes frequent ES timeouts. Any idea why this might happen?

It sounds like you are overloading your cluster and may need to scale up/out or limit the load. Do you have monitoring installed?

I would recommend upgrading, at least to the latest 1.7 release.
