Increase in CPU Usage with Unified Agent installed

• Web Security Service - WSS

Issue/Introduction

Unified Agent (UA) is causing excessive CPU usage, but no additional network traffic. UA is sending +10Mb/s traffic to the loopback address.

Cause

UA and the BCUA Notifier are communicating with each other, by design, on the local machine and are creating the traffic on the loopback address.

Resolution

Even though the traffic on the loopback address is normal, you can reduce the amount of traffic by stopping the bcua-notifier process and preventing it from running on system startup. This will cause you to lose access to the UA GUI, the option to reconnect UA, and status and version information.
