I know this is an old post fronm April 2013, and the OP got round his
problem, but I feel it is probably worth repeating the gist of a post I
made recently to the Pluto Users mailing list after a similar problem...
The problem may be caused by some of the articlesnn files in
!Pluto.Articles (nn=0-63) or an external box (nn=0-31) going over 16MB in
size. [For the OP, the 900MB total was an average of 14MB per file, so I
suspect some would have been over 16MB]
When this happens, the offset of the start of an article from the start
of the file is truncated because only 24 bits are used, and the file
number is then corrupted because that is in the top 8 bits. When these
values are used from the index (even after rebuilding the index) it
cannot find the article, hence the Index error.
There seems little checking for this limit in Pluto for external boxes or
the main files, so I would *strongly* advise users to make sure that
their articles files remain under 16MB each.
Note that the files can actually go over 16MB without problem, as long as
the offset of the start of last article is below 16MB, but that is
difficult for a user to see.
If anyone finds they have any Pluto articlesnn files over 16MB, please
contact me at my Pluto address in the Help manual.
In the StrongHelp manual the 'Frequently Asked Questions' leads to 'How
do I Reduce Pluto space/memory?' which often gives an easy way to reduce
space usage.
