Troubleshooting requests not executing, High CPU usage, and the "Failed to fetch system information" message in VMware Aria Suite Lifecycle

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

Possible Symptoms:

• Aria Suite Lifecycle appliance VM exhibits high CPU utilization triggering "Virtual Machine CPU usage" alarms in vCenter Server. 
  
  
• Running the top command shows the postgres service as one of the highest CPU-consuming processes.
  
  • Press Shift + P while top is running to sort processes by CPU usage.
  • Alternatively, run top -o %CPU to sort directly by CPU consumption.
    
    
• CPU usage remains consistently elevated in the vSphere Monitor tab for the virtual machine.
  
  
• Accessing Home > Settings > System Details on VRLCM fails with the error: "Failed to fetch system information".
  
  
• Other UI operations, such as log bundle generation and routine Day 2 tasks, do not complete successfully.
  
  
• Overall UI navigation is noticeably slow or unresponsive.
  
  
• A red banner appears under the SSH Information and FIPS Mode Compliance section in Settings, without displaying a specific error code.
  
  
• Triggering Inventory Sync for a product remains in a loading state indefinitely, with no error shown in the UI. After refreshing the page, the request disappears from the Requests page.

Environment

VMware Aria Suite Lifecycle 8.x

Cause
