23 Mar 2017: MetaKGP server ran out of memory and started showing errors on the Wiki. Server was restarted but didn't come up. @defcon restarted the server from the DigitalOcean webconsole and it came back online after a downtime of 30 mins. ElasticSearch+ was consuming about 20% of the memory.
27 Jan 2016: metakgp server ran out of space. Deleted unnecessary files, and restarted the server. Ran into 500 Server Error. Investigated and found in the php error log (/var/log/php-fpm/error.www.log) that there was a problem in LocalSettings.php. Removed the offending lines, and restarted php - everything works now!
