Am I missing an obvious problem in the SWFUpload integration logs?

Used the wrong server variable in the last post. According to the logs, a file is being sent, but somehow it's getting lost during "$this->upload->do_upload('Filedata');".

Code:

log_message('debug', '***: '.$_FILES["Filedata"]["tmp_name"]);

Log file:
DEBUG - 2010-01-02 00:03:06 --> ***: /usr/local/tmp/php0IRFYk
