Fix “Runtime Exited” in AWS Lambda for IronOCR

If you encounter the following error, it is highly likely that the issue is related to insufficient memory allocation:

RequestId: 48ace8f3-1391-40ea-bc0e-aa864de3a8e2 Error: Runtime exited with error: 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.

Increasing the memory allocation allows the Lambda function to handle larger tasks, potentially eliminating the "Runtime exited with error" issue. Make sure to test the function after making changes to ensure it performs as expected.
