Sudden issues with 512MB Ubuntu 14.04 WordPress droplet
The droplet was created with WordPress on Ubuntu 14.04 image.
I’ve had a WordPress site (with probably zero traffic) running for a while now. Suddenly I noticed it reported a database connection error, fair enough. So I checked:
“service mysql status”
That returned stop/waiting, fair enough. Easy to get back running. It then crashed again eventually, and so forth.
I read up and noticed comments on creating a swap, which I then did exactly according to this guide.
“free -m” shows:
total used free shared buffers cached Mem: 490 485 4 12 0 20 -/+ buffers/cache: 464 25 Swap: 4095 897 3198
The result of adding swap?
My droplet is sometimes super slow while accessing it via SSH, i.e. typing into it lags. Never had this before, so I assume it is related.
Also, the website doesn’t respond any longer. Ever. Sometimes the browser gets past connecting, but never past waiting.
What went wrong? Which logs should I check?
Surely a WordPress without almost no traffic shouldn’t have issues on even the smallest droplet. I’ve previously had a few sites running on the 512MB perfectly fine.
