When I log into my machines after an apt-get upgrades, I often get this message:

  System load:  0.06              Processes:           86

*** System restart required ***

Obviously, restarting a production server is not something I'm keen to do very often.

Why is *** System restart required ***? What risks do I take if I don't restart it?

@Parto My question is more specific than the one you've linked to - I am asking about EC2 servers. – Adam Matan Jun 16 '14 at 15:28
EC2 servers are a just subclass of all other Ubuntu systems. The answer is the same. – bain Jun 16 '14 at 23:01
I think the aim of Adam is actually to find an answer to: "what do I need to do to ensure maximum uptime?" but correct me if I'm wrong. – Andrea Corbellini Jun 18 '14 at 19:12
