cloudwatch_lambda_agent error using latest python images

Hi — apologies if this is the wrong repo.

Since the latest AWS Lambda base images were published, we’re seeing repeated error logs inside our Lambdas:

```bash
[2025-11-25T23:11:17.882Z ERROR cloudwatch_lambda_agent::utilities::cgroupfs]
Error while reading memory.stat for path /sys/fs/cgroup/memory/memory.stat:
No such file or directory (os error 2)
```

This error appears with the newest image tags, but does not occur with older images such as:

- `public.ecr.aws/lambda/python:3.11.2025.11.22.10-x86_64` with
```
RUN curl -O https://lambda-insights-extension.s3-ap-northeast-1.amazonaws.com/amazon_linux/lambda-insights-extension.rpm && \
rpm -U lambda-insights-extension.rpm && \
rm -f lambda-insights-extension.rpm
```

- `public.ecr.aws/lambda/python:3.12.2025.11.22.10-x86_64` with
```
RUN curl -O https://lambda-insights-extension.s3-ap-northeast-1.amazonaws.com/amazon_linux/lambda-insights-extension.rpm && \
rpm -U lambda-insights-extension.rpm && \
rm -f lambda-insights-extension.rpm
```

Repro steps (what we did):

- Pull latest image (e.g. public.ecr.aws/lambda/python:3.11) and run a simple Lambda that initializes the CloudWatch agent.

- Observe repeated memory.stat read errors in the logs.

- Repeat with the older image tag listed above — no such errors appear.

Expected behavior: no memory.stat read errors in normal Lambda container environment.

Actual behavior: repeated cloudwatch_lambda_agent::utilities::cgroupfs errors about missing /sys/fs/cgroup/memory/memory.stat.

Environment details:

- Images tested: latest published Lambda base images (tags pushed recently)

- Images that do not show the error: public.ecr.aws/lambda/python:3.11.2025.11.22.10-x86_64, public.ecr.aws/lambda/python:3.12.2025.11.22.10-x86_64

Thanks for any guidance — happy to provide more info or help debug.
