It's a really small box (512mb) that runs everyting and on a normal day it does not have any issues but when the requests from HN started coming in Apache used up all the RAM. I stopped Apache and started Mailtrain from command line in a screen session to listen directly on the web ports (so once it's out from the HN frontpage I can reboot the VPS and everything gets back to normal settings). So far it has been running smoothly with the server RAM usage in a constant 50%, no fluctuations https://cloudup.com/cokRbDpMIuw
