what is “mynokia” process? never seen it before

You need to first track why CPU is high. In your screenshot mynokia is eating up CPU so what is does? Then you need to find out if an excess amount of requests resulted in that or not. Then investigate request for legitimacy (or part of an attack)…
You need to move up from CPU usage to the higher level reason then you can peek right technology/tools of CF for your problem.
