Splunk service needs to be restarted to keep it running. How do I resolve it?

Hi, I have a t2.micro linux instance running as a Splunk node. The splunk instance sometimes doesn't pass status checks on AWS. When I stop and restart the instance again, it works. I SSH into the instance and check the status every time I cannot access the home page. It shows that the splunkd is not running. I restart the process and then I can access the Splunk page on port 8000 again. Please help me resolve this issue. Thank you. Sai
