Report on failure of server NC020

3 June 2009 03:45:36 +0000

The cause of the problem with NC020 was a website that overwhelmed the MySQL database server, causing the server to kill MySQL and run out of memory. As a result, although the server was technically “running”, all processes failed and no connections could be made to the server. A hard reboot brought the server back online.

The problem with the website in question is being addressed, and this shouldn’t happen again.

It should be noted that server NC020 is a secondary server, generally for specialised projects and functions, and this incident affected almost none of our clients.
