OSError: [Errno 28] No space left on device - AWS Lambda + Zappa

I have deployed an application on AWS lambda using Zappa. I get the error in zappa tail - OSError: No space left on device. The file size is large so I am using S3 as well. Below is my zappa settings.

{"dev": {
"app_function": "app.app",
"profile_name": "default",
"aws_region": "------",
"project_name": "----",
"runtime": "python3.6",
"s3_bucket": "------",
"timeout_seconds": 300,
"slim_handler": true
}
}

below is the stack trace:

Any suggestions?

Solution

  • It was a memory issue. Cleaning up the code and the virtualenv solved the problem. Removed extra libraries which were not required to reduce the space.
