Could you try exporting the $TMPDIR var before starting the passenger
processes?

This is the code that generates the temp file (sunstone-server.rb):
        tmpfile = Tempfile.open('sunstone-upload')

by default, it uses Dir.tmpdir as temp dir and this method checks the env
var TMPDIR.  This variable is defined in the sunstone-server script, but
Apache do not use this script to start new server instances

You can also specify it as a parameter in the code:
        tmpfile = Tempfile.open('sunstone-upload', '/mnt/sunstone_upload')

Hope this helps
