I’ve just received the following:
One or more of your Droplets is nearing its memory capacity and its performance could be affected. Without sufficient RAM or memory, applications might run slowly, or can occasionally become unstable and crash.
I’ve a 2GB memory digital ocean droplet.
Over the last 14 days the graph shows about 90-95% memory usage. I asked about memory etc a while back and apparently it’s good to be using what’s available, but this is the first time Digital Ocean has emailed about it. I’m on 2.8.0b6.
The only recent change I can think of is that I set all users to “watch” the main categories, and so receive email notifications, and maybe because of that there have been more posts - but it’s still a relatively quiet forum with about 250 users and a handful of active posters.
What might be causing this, and what should I do, if anything? Or what further information would be helpful? Thanks.
Update. If it helps: disk usage is constant at under 40% and CPU is under 5% with occasional spikes up to about 20%.
