I’m using a 2GB Digital Ocean Droplet and I keep getting 500 errors when users are trying to post new comments.
I checked the server logs and I see them full of these 2 lines:
44:M 22 Feb 12:10:04.079 * 1 changes in 900 seconds. Saving…
44:M 22 Feb 12:10:04.079 # Can’t save in background: fork: Cannot allocate memory
Also, when I ssh into my droplet, I see that memory consumption is at 82%.
I tried updating everything to latest, resetting the machine, but nothing helps on the long run. It works ok for a bit an then starts throwing the errors again.
