CPU utilization 100% continuously on windows servers

Question

Team,

I have Windows Server 2019 standard edition servers in my environment where my agent connects remotely it is observed my CPU utilization is spiking and increasing to 90 to 100 %.

=========================================================

Below is the observation

Noticed that CortexXDR and PowerShell sessions exhibit intermittent CPU utilization spikes every minute, returning to normal after a few seconds.

The primary issue observed is CortexXDR intercepting all incoming and outgoing network traffic. Since PowerShell sessions involve remote calls/commands, they are intercepted by CortexXDR every minute, significantly impacting their performance. Due to PowerShell sessions caught up by CortexXDR, both CortexXDR and PowerShell sessions exhibit higher CPU utilization than usual (only during the periods when they hang with CortexXDR).

Suggested turning off CortexXDR and Symantec, which is not feasible and cannot be turned off due to Security concerns.

================================================================

Site controller configuration

Each server with Socket 2 and Virtual processor 12 and Few Server with Virtual processor 16 total we have 6 servers in the Mumbai site and 3 servers in Bangalore site and all are showing higher utilization due to which servers goes in hung mode impacting all connected agents showing down. Requesting you to please suggest with the remediation.
