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%.
Thank you for the quick response. It could well be a glitch (in which case there might be more replies like yours!) but in my case the graph was bouncing about in the 90-95 range for the full two weeks. I guess the graph could be wrong too…
I take that back - I have a test droplet that I hadn’t checked and that’s the one that likely triggered the warning. I’ll rebuild it and see what happens.
No significant change after an update, reboot, and rebuild. This is a minimal droplet I use just for testing and it’s normally dormant with CPU at ~1% and no users besides me.
In my case, in the first few minutes at least, it seems to have gone down significantly. I’ll keep an eye on it. I ran ./launcher rebuild mail-receiver followed by ./launcher rebuild app at about 1205.
11% available as shown with free -m and 12% from the monitoring graph, so it’s pretty close (rounding error). This graph is the only measurement the DO panel provides for memory in the Admin panel.

It didn’t last though. At first I thought it might have happened because I recently migrated it from another host to DigitalOcean, but it seemed to be fine for a while after migrating. I’m probably going to upgrade to 4 GB RAM later today.
