There are many questions about this on django-users. The usual answer
is to ignore the errors, which are probably generated as a result of
the client prematurely terminating a connection, usually during an
upload.
Nobody seems to be able to reliably reproduce the error, and it seems
to happen with large and small uploads alike, but always
intermittently.
It has been suggested that a client dropping the connection should be
within what one can expect from a networked client, and thus Django
should not email the exception and traceback to the admins in this
case. From my preliminary investigation with this issue, I tend to
agree.
Is it feasible to handle this exception in Django, or are there other
issues that would prevent us from isolating this case from other
legitimate exceptions that may be raised at this point?
Here's a recent traceback:
