| orthe is a diskless indigo/4000 connected to server insti (also R4000
| indigo).  We have been experiencing many problems with the diskless
| machines since upgrading to R4000's and this message has been
| appearing often.
| 
| The problems are that, starting the day after they (5 of them) were
| upgraded, occasionally when someone logs out, the display goes black
| with little flashes of light all over the place.  I would *guess* that
| it's either a problem with XDM or Xsgi since it only seems to happen
| when someone logs out.  We have xdm terminate and restart the X server
| whenever someone logs out to avoid the X server's size growing.  We
| installed a new 405F diskless share/client tree when the machines were
| upgraded.  The diskless machines all have entry graphics, while the
| server is an XS.  The diskless tree was configured for entry though, and
| they work fine 98% of the time.  Each machine seems to go OK for a few
| days (say 20 logins) and then the display problem happens.  TAC has never
| heard of this problem but also suggests it is a software problem.

There is a known bug that can occur on logout under both 405 and 405F
on an Indigo.  It is 'rare', but it happens (better under 405F than 405).
It does seem to affect some configurations more than others.

| Any help/info appreciated, on either this or the write errors (or both if
| they may be related)!

The write errors aren't related.  error 13 is 'permission denied'.  Probably
some file is being written as root, but that gets turned into 'nobody'
because of the way the filesystem is exported.  See 'man exports' for
more info on that.
