Bug: sam sync with python causes endless cpu saturation
Description:
When running sam sync --watch --region us-east-1
on a python project, the sam sync
process utilizes 100% cpu until I kill it (after at least 30 minutes)
Steps to reproduce:
- Create a new python project using sam init.
- Use python3.11
- Run
sam deploy --guided
- Run
sam sync --watch --region us-east-1
After it has deployed the application and the CPU utilization has gone down, it suddenly goes to 100% and stays there.
Observed result:
