Lightsail instance slows down and website stops responding

Question

Hi there,

I have many Lightsail instances for small, low demand websites. I have one though which I setup around 18 months ago. Recently, in the past few months it has been alerting me to the CPUUtilization being too high and it the site fails to respond.

I am able to restart the instance it and then it was fine for a few days more. Now though, it only lasts a matter of minutes. I managed to get in and update Wordpress and plugins. I am not sure how to troubleshoot it further if it is completely non respnsive. Wordfence has now given me any errors either.

Domain: https://cloverleaf3d.xyz/
Instance: 512 MB RAM, 1 vCPU, 20 GB SSD

Monitored Details:
- MonitoredResourceType: Lightsail/Instance
- MonitoredResourceName: Cloverleaf3D
- ComparisonOperator: GreaterThanOrEqualToThreshold
- Threshold: 5.0 Percent
- MetricName: CPUUtilization
- Period: 300 Seconds
- Statistic: Average

Any help to diagnose would be really appreciated.
Thanks!

Answer

Thank you. I honestly think it should be OK as the site is so lightweight and almost no traffic. I think I may have diagnosed a plugin conflict.
