Describe the bug
We have observed sustained high CPU utilization caused by the AWS CLI Python runtime on our Windows Server 2022 Datacenter instance.
Issue Details:
Duration: 5.5+ hours of elevated CPU consumption
Process: Python runtime from C:\Program Files\Amazon\AWSCLI\runtime
CPU Impact: 59.3% sustained usage
Instance Type: r6id.4xlarge (should have sufficient resources)
Environment:
OS: Windows Server 2022 Datacenter
AWS CLI Version: aws-cli/1.37.15
Python Version: 3.12.6
Botocore Version: botocore/1.36.15
Exec Environment: EC2
Related AWS Case:
AWS Support case ID: 178882204600949 (opened for investigation)
Additional Context:
This is not typical behavior for our environment. We have not previously observed AWS CLI consuming this level of CPU resources. Task Manager screenshot attached showing the Python process and its child processes (Background Intelligent Transfer Service, WMI Performance Adapter, etc.).
Request:
Please investigate whether this is a known issue with aws-cli/1.37.15 on Windows Server 2022, or if there's a configuration/bug causing excessive processing.
Regression Issue
Expected Behavior
AWSCLI runtime CPU usage should have been very low, not even 1%.
It shouldn't be flat lining the CPU for 5.5 hours.
Current Behavior
CPU came back to normal automatically after the case was raised with AWS
Reproduction Steps
I haven't seen this issue before
Possible Solution
No response
Additional Information/Context
No response
CLI version used
1.37.15
Environment details (OS name and version, etc.)
Windows 2022 Server Datacenter
