Hi All,
I've got a Django app that accepts uploads from jQuery uploadify, a jQ plugin that uses flash to upload files and give a progress bar.

Files under about 150k work, but bigger files always fail and almost always at around 192k (that's 3 chunks) completed, sometimes at around 160k. The Exception I get is below.

exceptions.IOError
request data read error
File "/usr/lib/python2.4/site-packages/django/core/handlers/wsgi.py", line 171, in _get_post
    self._load_post_and_files()
File "/usr/lib/python2.4/site-packages/django/core/handlers/wsgi.py", line 137, in _load_post_and_files
    self._post, self._files = self.parse_file_upload(self.META,     self.environ[\'wsgi.input\'])
File "/usr/lib/python2.4/site-packages/django/http/__init__.py", line 124, in parse_file_upload
    return parser.parse()
File "/usr/lib/python2.4/site-packages/django/http/multipartparser.py", line 192, in parse
    for chunk in field_stream:
File "/usr/lib/python2.4/site-packages/django/http/multipartparser.py", line 314, in next
    output = self._producer.next()
File "/usr/lib/python2.4/site-packages/django/http/multipartparser.py", line 468, in next
    for bytes in stream:
File "/usr/lib/python2.4/site-packages/django/http/multipartparser.py", line 314, in next
    output = self._producer.next()
File "/usr/lib/python2.4/site-packages/django/http/multipartparser.py", line 375, in next
    data = self.flo.read(self.chunk_size)
File "/usr/lib/python2.4/site-packages/django/http/multipartparser.py", line 405, in read
    return self._file.read(num_bytes)

When running locally on the Django development server, big files work.
I've tried setting my FILE_UPLOAD_HANDLERS = ("django.core.files.uploadhandler.TemporaryFileUploadHandler",) in case it was the memory upload handler, but it made no difference.

Does anyone know how to fix this?
