How much memory does your instance have? I would consider 8Gig a minimum for actually building the node from source.

Hi Erik,

it looks like I selected a wrong instance type (Carlos is using 4 Gib, and I selected 1).  
I will try 8 just to be sure.  
Thanks for your help!

Very likely that you run out of memory.
