Is it a physical server or virtual server ? – Lawrence – 2013-12-18T12:30:45.430

Is this just a physical ubuntu server, or is it a virtual machine? If so, what virtualisation solution are you using? – Mark Booth – 2013-12-18T12:31:32.727

3You won't be able to upgrade the memory without doing a restart. – Ramhound – 2013-12-18T12:35:48.637

Upgrading a RAM takes about 3 minutes. Your live system may well die and then resurrect. – MariusMatutiae – 2013-12-18T12:38:05.583

@Ramhound, any alternate solution, to keep alive server processes. – user1635700 – 2013-12-18T12:38:18.510

@user1635700 - What you want is not possible with the hardware your using. – Ramhound – 2013-12-18T12:45:43.963

1You should not ever add RAM to a live system. What are you running that is so important that you cant take it down for 20 minutes at 4:00 AM? – Richie086 – 2013-12-27T07:23:07.097

You won't be able to hotswap RAM while the system is running unless you are using high class enterprise level hardware.

Unless you have 2 servers for failover, your processes will need to be restarted when the server restarts.
