Infrastructure agent (IA) is by default configured with 512MB that might not be the appropriate for the monitor(s) in use.
You must adjust the IA heapsize based on your tests and requirements.
Suggestions:
1. Increase heap size memory: we recommend to configure the Infrastructure Agent for AWS monitor with a minimum of 1 GB to prevent the Out of Memory issue
