title: Jenkins crashes on npm install
body: <p>I'm trying to build our code through jenkins. I set it up 4 days ago and everything worked back then, but now every build fails. At first I thought it was because of the Jest testing I added (jest kept hanging instead of stopping) but I fixed that with --forceExit and the problem still exists.</p>
  
  <p>With every build, it seems like Jenkins is crashing silently. I couldn't find any useful logs or anything. What is weird though, is that I tried to execute the commands through ssh in the jenkins folder where the project was placed by jenkins. When I did that, the npm install was really slow and the whole server was hanging. There are two other projects running from that server with nodejs, one with keystonejs that crashes every time this happens, the other one is plain express and had no problems. Any idea what can be the problem here?</p>
  
  <p>EDIT: It's also happening more randomly and I couldn't connect to my server for a while through ssh or any other possibility.</p>
