AWS Lambda - Runtime Exited Signal: Killed

Reason

This error typically occurs when the application tries to execute a task that exceeds the available memory on the host machine or container environment. When the memory consumption reaches the system's limit, the process is forcefully terminated, resulting in the "signal: killed" message.

Solution

To increase memory for an AWS Lambda function:

1. Go to the AWS Management Console.
2. Navigate to Lambda > Functions.
3. Select the function experiencing the issue.
4. Under the 'Configuration' tab, choose 'General configuration' and click 'Edit'.
5. Adjust the memory allocation and save.
