Hey @floatinglapisraft,
Can you confirm what do you mean by website not working at all, do you see a white screen is your webserivce down or does it keep going down?
First, I noticed that you have 1.0GiB of RAM according to the logs. Try adding some swap to have a failover state when you reach the 1GB of RAM:
https://www.digitalocean.com/community/tutorial_collections/how-to-add-swap-space
What is Swap
Swap is a portion of hard drive storage that has been set aside for the operating system to temporarily store data that it can no longer hold in RAM. This lets you increase the amount of information that your server can keep in its working memory, with some caveats. The swap space on the hard drive will be used mainly when there is no longer sufficient space in RAM to hold in-use application data.
The information written to disk will be significantly slower than information kept in RAM, but the operating system will prefer to keep running application data in memory and use swap for the older data. Overall, having swap space as a fallback for when your system’s RAM is depleted can be a good safety net against out-of-memory exceptions on systems with non-SSD storage available.
#PHP Errors
According to the logs, you have the following errors:
These errors will not necessarily result in a big problem however you might be missing some data from your website. They show that you are trying to access some values that are not there
Configuration Errors
These errors point to some issues with your configuration o
More Configuration errors created by your website’s code
These as well:
If you read them closely, it seems your request is timing out, possibly because of your code. You’ll need to further investigate where is this timeout coming from, it should be from somewhere in your code
Hello @floatinglapisraft
I believe this can also occur when the droplet is running out of memory. What I can recommend is examining the logs and checking if the droplet is having issues with its RAM.
You can add a swap to the droplet (if not done already)
https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-22-04
You can also check which processes are consuming the memory of the droplet using tools like
topnetstatand others.https://www.digitalocean.com/community/tutorials/how-to-use-top-netstat-du-other-tools-to-monitor-server-resources
Hope that this helps!
