The error suggests the mongo lock file is present so mongo refuses to start up again.
If you're sure mongo isn't running, just delete the lock file.
currently I have my server in Google Cloud and I've been receiving several traffic spikes due to promotions we launch on social media.
I'm wondering, has anyone put their server on the cloud and is using autoscaling (by creating multiple instance groups).
If so, what's your configuration like? How can I scale NodeBB this way? (Those traffic spikes tend to kill my CPU fast).
