Interesting. So what was the actual exception type? - the docs state that WebRequest() only throws WebException exception and I would have thought that would contain : (0x80004005): Maximum request length exceeded.
BTW If you are putting such an high limit I'd suggest limiting its scope to the relevant page - and even then make it no bigger than it needs to be in practice.
