I have a trouble with CPU utilization when I start the gateway : 100% all the time. I use Jessie and not Wheezy on a RPI 2. Does someone can help me to troubleshoot this problem ? I have not add a decoupling capacitor , can it be the reason ?

This happened to me as well, I mixed up the boards I had at home and discover later it was a B+ and not a RPI2 :-) Maybe you've made the same mistake?
