[FreddieAkeroyd]

According to nagios, on NDXIMAT

CRITICAL (Sample Period 601 sec) - [Triggered by _AvgCPU>85] - Found 1 Instance(s) of "ibex-client" running. CPU_ibex-client(PID=24208)=180.7%

acceptance criteria

• it is understood why client is now using so much CPU and appropriate tickets to fix are created
