It oddly seems to have stopped happening when we moved to staging.
It's a different server though the apache config is exactly the same
(the settings I sent in my previous message: mod_wsgi 3.2, embedded
mode, mpm worker). We also rolled out a few fixes in our mobile app so
it's possible it was b
BTW, you didn't say whether you were using mod_wsgi embedded mode or daemon
mode and what latter configuration was if using it.

Any chance you can do some tests, if you yourself can replicate it, of
whether it fails when using straight http. Most times I have heard about
this, it is somehow specifically related to use of https conn

Presuming Apace/mod_wsgi is being used, are you using https or just http? Are
you using daemon mode of mod_wsgi? If yes to latter, how have you configured
daemon mode? Also what Apache MPM are you using and what MPM configuration
settings? Finally, what Apache and mod_wsgi versions are you using

Did you ever track down what was happening ?
Was any more information discovered on this problem ?
I'm seeing a similar issue in a eb service written in Django which
receives data from mobile apps as a POST. Not infrequently, I'm
seeing the same "IOError: request data read error" when I try to
As a datapoint, I've had 9 of these errors from 5 different people (2
people retried 3 times each) and 30 successful uploads from 14
different people in the past 7 days on a low traffic site (300
visits).
That's a pretty low success rate. Seven of the errors had a user agent
indicating MSIE 8, one
Well, if this is a problem with WSGI, why not enhance the
specification in the way Graham proposed? I'm sure that whoever is
responsible for writing the spec is open for suggestions like this one
(while WSGI attempts to be as lean as possible, I'd say that not being
able to reliably know when a con

It seems to happen with very small file uploads as well. I've seen it reported
with 30KB uploads, while at the same time 60MB uploads work. If I can't find a
problem with the server causing disconnects, and it is actually on the client

Have you considered the possibility that it would be a client/browser
side error?
Both windows7 and chrome have a known open bug with large file
uploads. Many of my customers have reported this bug, all of them
using windows7 and chrome.
Has anyone seen this happening from a Mac or from Linux?

Thanks for your detailed explanation, Graham. I'll try to approach
this from another angle and see if I can determine what is actually
causing the connections to be dropped, as I'm seeing this error a few
times a day on a low traffic site using Apache at the front for static
media, with proxy pass
The problem is you can't just catch IOError, because the presence of WSGI
middleware may mean that IOError could be generated for other reasons when
reading wsgi.input. To base detection on the description in the IOError,
ie., 'request data read error', would mean having to know what that

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
