Environment: Solaris
Using a pool of machines, I need to be able to start some jobs
on different machines, each of them running under X display (the
job is embedded into a short script which opens a vnc session on
the machine).

Here is a part of the launch script:
    set nvclog = `$XVNCHOME/vncserver -depth 24 -nolisten local |&
/bin/grep 'Log file is' | /bin/awk '{print $4}'` # runs the server
    set nvcdisplay = `basename ${nvclog:r}` # and gets the display host
and port


During its execution,the job sometimes run into trouble and cannot
access the X display. Here is the message I sometimes (unreproducible)
get
from my application ():

> Xlib: connection to "cdssoph38:1.0" refused by server
> Xlib: Client is not authorized to connect to Server
> xwd: unable to open display 'cdssoph38:1'
> usage: xwd [-display host:dpy] [-debug] [-help] [-root|-id |-name ]
[-nobdrs] [-out ] [-xy] [-add value] [-frame]
> xwdtopnm: couldn't read XWD file header
4d8

Do you know any possible reason for this problem?

Thanks,

Olivier.
