Subject:   -70- Why do I get a "Broken Pipe" error when I close an X
                client window?
Date: 10 Jun 1993 00:00:01 EST

  Typically the error message looks like:  XIO: fatal IO error 32
  (Broken pipe) on X server ":0.0" after 214 requests (214 known
  processed) with 0 events remaining.  The connection was probably
  broken by a server shutdown or KillClient.

  The Window Manager is reporting that the pipe for your X client has
  been broken.  This is normal when an X client exits.  There is
  nothing wrong with your system. This message will also occur when the
  system is shut down.  This is not an error condition and no core
  files are produced.
