I was attempting to spit out an error message from a Soap call, and the error message was longer than 2000 characters, which resulted in the url being longer than 2015 characters (maybe thats the limit for CRM online?) and errored. The Call should limit the message to less than 2000 characters, maybe by limitting to 1990, and added "-snipped-" to the end?
Without this limit, a 404 is returned.
