File empty on all asset uploads

Question

I've already adjusted the php.ini with max values for timeout and file size. This is really perplexing me. I'm on Dreamhost VPS. I've triple checked all file permissions. I consistently get this error: "Upload failed for brooklyn_bridge.jpg. The error message was: “Error uploading the file: Uploaded file was empty" no matter what I try.

Here was a recent error after turning devmode on:

$_FILES=array (
  'assets-upload' => 
  array (
    'name' => 'brooklyn_bridge.jpg',
    'type' => '',
    'tmp_name' => '',

    'size' => 0,

It was an issue with the /tmp folder filling up. Have to regularly make sure it's emptied. If the /tmp folder has proper permissions this should happen automatically.
