I've had the same problem, and can't figure out how to resolve it. It seems to have nothing to do with the amount of data being transfered: it happens occasionally on the smallest of page requests/responses. It also doesn't seem to be related to browser, unless several different versions of IE *and* Safari have the same problem. I tried disabling keepalives for Safari at least, and it doesn't seem to have helped. I'd prefer not to disable keepalives in general, if I can avoid it.
All of the error messages I've received have shown in the traceback that they're coming through this function: http://code.djangoproject.com/browser/django/trunk/django/core/handlers/wsgi.py#L131 It seems to me like there's an easy workaround (I'm sure the actual fix has to be much lower level, in WSGI or Apache [or even lower]) that would at least stop my users from getting 500 errors: wrap the contents of that function in a try block, and *don't* raise the exception. Otherwise, I'd have to wrap every view that uses POST in that, which would be very annoying. Or maybe write middleware that just peeks at POST before anything else gets it, so that I could catch it there. Thoughts?
