>> Reviewing your original post, it has occurred to me that your problem could be a symptom of an issue a number of sites are seeing with callback breaks. Essentially, it is possible for the thread in client that handles incoming network traffic to hang whilst handling a callback break. If this happens, it appears to the fileserver like the client is no longer handling data, and you will see the errors that you have been seeing.
