Simple solution is move to m1.xlarge :)

of my 3 nodes cluster.
The node is not able to keep up with the load. 

Possible causes include excessive GC, aggressive compaction, or simply too many requests.

it also a good idea to take a look at iostat to see if the disk is keeping up. 

Hope that helps
