### bndiagnostic was not useful. Could you please tell us why?

Unsure of cause

### Describe your issue as much as you can

After several days, CPU usage goes to 100% and sites are unavailable and SSH connects but produces no output. Can not reboot server or "stop" it. Have to force stop it and start again.

It seems the machine is running low on resources. I recommend upgrading it to a more powerful one.

[jason5591]

Is there a command to watch for low resources? We're trying to budget. We didn't have any trouble with the lower tier lightsail plan but now have the problems with this higher end one. Unfortunately, can't downgrade, only upgrade.

[mdhont]

You can check RAM usage of the machine with the following command:

free -m

And you can check disk usage with:

df -h

This Issue has been automatically marked as "stale" because it has not had recent activity (for 15 days). It will be closed if no further activity occurs. Thanks for the feedback.

[github-actions]

Due to the lack of activity in the last 5 days since it was marked as "stale", we proceed to close this Issue. Do not hesitate to reopen it later if necessary.

[jason5591]

To provide a solution to anyone else in the future. Bitnami builds are not built with any swap storage. So when a process runs that takes a lot of resources and an out of memory issue occurs, it will crash. At least in my case. I followed a guide online to create a swap space and it solved the issue.
