I just replaced the mother board in my SPARCstation 1+.  The machine
had been crashing a lot, and finally would not pass the cache or
register self-tests.

The new motherboard seems to work alright, except that OpenWindows 2
won't run (I am running SunOS 4.1.1).  If I use my old .openwin-init
file, one that I had been using for months, OW will not even come up.
Instead, it works away for a while and then produces the following
message on the screen:

XIO:  fatal IO error 32 (Broken pipe) on X server ":0.0"
      after 87 requests (86 known processed) with 31 events remaining.
      The connection was probably broken by a server shutdown or
      KillClient.
/usr/openwin/bin/xinit:  connection to X server lost.

Also, "xnews" leaves a core file in my home directory.

If I remove my .openwin-init and .Xdefaults file, OW 2 will start, but
will crash after a while, returning me to the non-windowed console.
This often happens with no error messages.  It seems to be somewhat
related to the number of window applications that are running --
adding more will increase the likelyhood of a crash.

This is a standard configuration of OpenWindows -- a simple
stand-alone machine.  Just to be sure, I reinstalled OW from scratch
from the CD-ROM, with no change in behaviour.

The supplier of the replacement board says that "this looks like a
software problem, and not a problem with our new board."  Has anyone
seen anything like this before?  Are there hardware problems that will
cause this kind of behaviour?

Other details that might be relevant are:
