CPU over usage

[athoscouto]

Describe the bug

Some of the pods of this app use way more CPU than others.
This may be caused by a resource leak and causes increase in latency and timeouts of the requests that hit the specific pod.

For instance, we have a single pod with average usage of 1.2 CPU cores, while another couple of pods are using around 0.5 pods.

To Reproduce
Steps to reproduce the behavior:
Just look at IO Deployments Grafana dashboard a few hours after a deploy has happened.

Expected behavior
Pods should have similar CPU usage so HPA can work properly.
