> 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.

Hi Simon,

Where I get more info on the callback break break problem? Does this 
affect windows clients? I'm wondering if we might be having this problem 
at my work.
