CPU usage Concourse

Hi,

Currently we have deployed concourse onto one of our VMs etc. and was wondering if I have deployed it correctly

As it keeps doing (img attached )even if its idle:

It used to build everything fine then suddenly just never finishes running its jobs etc. timeout etc.

Is there something I’m missing as this was fine then this suddenly occurred?

Concourse Version: v5.5.4

Help would be very much appreciated.
