I have one droplet that has 7 WordPress installs on it. Most sites get very little traffic so resources are not an issue.
However, every so often the CPU spikes to 100% and stays there. The only thing I can do is log into the website and power cycle the machine.

I believe that all of those reports of “out of memory” are related to lack of virtual memory. Digital Ocean droplets don’t come with swap partitions enabled by default, so the kernel just kill the process when it’s not possible to allocate more RAM for it
I had problems with a long-running Java process I developed and the solution was pretty simple.

Woo for the necro-posting.
I had this issue on one droplet a few months ago; I scaled up the droplet and hacked the MySQL config to pieces just to get the site working. Running another droplet, this time hosting multiple sites on it (all the same company) and constant disconnects.
Constantly breaking tables. I’m not even sure it is to do with the plugins/themes like I first thought.
It seems to be a running thing with DO droplets lately, as another client has had issues a few weeks back. And there is the whole “blanket blacklist DO IPs” too.
I have also the same issue. CPU cross 100% even if I open my site pages in mobile for viewing. mean I am only the user at that time on my site. still it. I have two magento 2 sites with 50 GB Space, 2 GB RAM and 2 GB Bandwidth. what should I do. each site hs only 70 to 150 products only
