title: .NET Webservice processing large file is having its thread aborted
body: <p>Let give you the details of this rather odd issue.</p>
  
  <p>We have a very large text file to process, it is 780MB and is likily to get bigger.
  The processing of this file lies in a .NET WebService, a request is sent from a Asp.Net Website client and the processing is started, then when completed returns to the Website.</p>
  
  <p>Before the file was being read via FTP and processed in about a minute.
  Now the file is being moved to a network share, but when the .Net WebService tries to proceess the file, the thread is being aborted.</p>
  
  <p>When I run the .net webService on my machine the processing is fine, and it completes (although very slow).
  When the .net WebService is placed on the webserver (hosted by IIS 6.0) it suffers the thread aborted exception.</p>
  
  <p>Any ideas?</p>
