I can\'t install node.js v0.6.1 on AWS EC2 (Ubuntu or CentOs - never mind). After installation I type node, and processor loads to 100%.
But v0.4.12 works fine.
I had the same / similar problem.
on standard 32-bit linux AMI with node v0.6, and redis package, if i opened node command line:
var redis = require('redis');
var r = redis.createClient();
r.quit();
the cpu would go to 100%.
I went to a ubuntu image, this time if I installed node v0.6, just running npm caused cpu to go to 100%.
What solved both situations was installing node v0.4.12.
