Sagemaker Autopilot Endpoint OutOfMemory

Good morning, I am encountering an unusual issue with Sagemaker Autopilot. After launching the training on my dataset and completing the entire process without any problems, the best model is deployed, and the endpoint appears to be functioning correctly. However, the issue arises when I attempt to call the endpoint repeatedly. I observe that the memory usage rapidly increases until it reaches 97%. At that point, it either crashes with the error message "worker died," and the CloudWatch logs indicate an "OutOfMemory" error in Java, or it remains operational but becomes congested. Upon reviewing CloudWatch, there doesn't appear to be anything abnormal except for the recurring message: "The column 'column_name' does not exist in your dataset. Please specify a different column name for the 'Input column' that actually exists in your dataset and try again." This message repeats even before I start invoking the endpoint. I'm uncertain if this is indeed the cause of the problem.
