Zend_Service_Amazon::getObjectSteam and copy() fail randomly

Michael Depetrillo
I have a command line process which downloads a video from Amazon S3 and
then re-uploads to another web service.

For some reason the call to copy() will randomly fail around 5% of the
time.  I've logged the error but I'm unable to make sense of the possible
problem.  Should stream_name be the path to my temporary file?  Is it
normal for the error message to only have 1 parameter for copy()?

This particular error did not appear the 2nd attempt to encode the file.
 I'm calling isObjectAvailable() before running the code below.

if (!copy($response->getStreamName(), $tmpFile)) {
            $errors= error_get_last();
            throw new Exception("Unable to copy file for Fliqz upload.
 Reason: " . print_r($response, true) . print_r($errors, true));
}
