Node.js program freezes on Amazon linux server

I have an ubuntu server on Amazon and I'm trying to run node.js. The program has only one line:

console.log('Here I am.');

Nothing happens, and the program does not exit.

when I run ps x, I can see one [node] process in STAT D state:

  751 ? D 0:04 [node]

The process cannot be stopped with sudo kill -9 751.

Before the problem, the node.js program went fine, as did my actual - much more complex - node.js program.

I even rebooted the ubuntu server and tried to run the node.js single-line test program right after the reboot. He hung and did not output anything.

node --version returns

 v0.7.6-pre

Any ideas why this is happening? Is this a problem with an Amazon instance, installing node.js, or something else? nginx works fine on a single server, but node.js programs freeze as described above.

(as expected, the same code works very well on my local mac os x environment)

UPDATE: I will go back to stable version 0.6.12, but the same problem persists.

The problem is solved (view).

It's a secret. I created a new instance on Amazon EC2 ("identical" to the one I had), installed git, nginx, node.js and my node.js. Now everything is working correctly.

Something must have happened to the instance I had. I just don't understand what it was, but since I had nothing important, I just dumped it.

Maybe the cause of this problem was version 0.7.6-pre, which I originally pulled out and compiled. Perhaps there were some errors from this installation that caused peculiar behavior.

Just for someone else who is facing this problem, it could be related to this:

"After using yum to upgrade to Amazon Linux AMI 2011.09, t1.micro 32-bit instances cannot reboot."

Updating "AKI" in my instance seems to fix the issue for me.
