The most common reason for this issue is that your MySQL process is exhausting the RAM your droplet has available. This then causes the service to crash. There are three steps you can take to resolve this:

1.) Set up a swap file on your droplet. This should prevent the crashes. 2.) Upgrade to a larger droplet with more RAM available. 3.) Optimize your MySQL and other services.

@ryanpq I just enabled a swapfile on one of my droplets. Since the error seems to occur randomly (not at times of high load) I’m not sure if doing this made a difference or not. Is there a way to stress test the effectiveness of an enabled swapfile? Thanks

@ryanpq why does this seem to be a continuous problem for wordpress installs on DO? I haven’t seen this issue across other hosts
