Noticed the website wiki is offline.

Any estimate on when this will be back online?

Bouncing it now.

The VM has limited memory and often runs out.

The OOM killer whacks the MySQL service which knocks the wiki offline.

Ugh, it looks like the VM memory problem is back. Restarted the MySQL service.

We got a bug report for the issue at
https://github.com/weidai11/cryptopp/issues/720 .

I setup a hourly cron job to check if the service was running and restart
it if not. The root cause is still present, but the cron job should contain
it so the service outage is intermittent.

OK, it looks like the script is doing its job. We had two OOM kills but the
wiki is available:
