Dear Wayne,
the only other file which was open besides the 28 ds9 files was unit
100, the log file. I just checked that the socket procedure itself
behaves fine (using the example from the manual), i.e. opens and closes
units correctly.
Thanks for pointing to ATV (I have an older version installed). However,
ds9 offers some functionality which is not (yet) available with ATV.
regards,
Bringfried

I suspect that other files are being opened besides the one opened and
closed by webget.pro. What does "help,/files" return?

P.S. DS9 as a fine astronomical display viewer, but you might also
look at Aaron Barth's recently enhanced ATV ( http://www.physics.uci.edu/~barth/atv/
) for something similar in IDL.

Perhaps this is a hint. I noticed that there dozens of defunct ds9 jobs.
I use "spawn" to pipe the images into ds9. After "close,/all" I can kill
them. But I am wondering whether this is the cause or the consequence of
the socket issue.
