c9 server gets killed all the time



I am having a pretty frustrating time lately as my server is constantly being killed. I’ve taken a look at my process list which looks like this http://i.imgur.com/hdC9rym.png but I’m not sure what I can and can’t get rid of. I’ve seen other posts on here about using a gem called spring but I’ve check my gem list and I don’t even have that gem installed. Any advice?
