There really isn't much of a kpdf development team any more,
since development 
of kpdf stopped with KDE3.

Okular is the functional replacement in KDE4.

I'd suggest that you either put in a bug report (if it is a
bug or security 
issue) or ask on the normal channels (e.g. the kdekde.org
mailing list, or 
an IRC equivalent). 

This isn't the right place for user questions.

You should mail the okular mailinglist. KPDF is renamed to
Okular in KDE 4 
check http://okular.kde.org/
(okular-develkde.org and #okular on IRC)

thank you Jos, Brad

i was a little misinformed about the kpdf->okular thing 
( i use an
old version of Pardus linux  that came with kpdf )

i will try in okular mailing list or irc channel

Or maybe have a look at Okular first, it might address your
issue (the one 
you're not telling us ).

i open a 2293 page PDF [1] , do a search on the document and
this
operation results in a machine freeze  ( too much memory
usage .. the
hard disk keep running and running , i lose control of the
GUI and
have to reset ) ( AMD Athlon 2.2GHZ 512 MB RAM, 1GB swap,
30GB hd free
space , Pardus Linux 2007.2 with KDE 3.5.7 )

may be this have to do with the "quality" of the
searching
implementation and algorithm that kpdf uses ... for this
reason i
thought that it would be useful to post my experience in
the
kde-qualitykde.org list

don't get me wrong, KDE and kpdf rocks ... this is an
"edge" case ( MS
OOXML specification monster

It does work here with KPDF from 3.5.8, but this machine has
2.5 GB of RAM, 
searching for "body" takes about 20 seconds. You
can setup KPDF's memory 
usage pattern in the config dialogue, not sure if it changes
a lot though. 
Did you try other PDF readers, btw?

Hehehe, Urghs. The meaning of that huge document is probably
not to have 
people read it, but to have people ignore it, but that's
politics.

thanks for that, i will try some tunning

on this laptop (2Ghz dual core system, standard laptopy SATA
drive), acroread 
takes ~1s to pop up and show that document, okular ~2.5s
(~.5s of that is 
okular start up time), kpdf from kde 3.5.9 takes a little
over a second 
(1.3-ish?).

acroread takes ~90MB RSS, okular ~36MB RSS, kpdf ~34MB.

okular takes ~30s to search the document for
"katakana", acroread takes ~18s, 
kpdf ~19s.

okular and kpdf has the benefit of a less screwed up UI and
has nice features 
like opening the document to the page i last left it at.

alos keep in mind that my okular is built with debug symbols
and was spewing a 
fair amount of debug output to konsole while doing this
unscientific 
measurement.

so all in all, not bad. it seems there's a tradeoff: raw
speed goes to 
acroread (though the real wall clock difference is a second
here or there), 
but UI and memory usage goes to kpdf/okular.

if any of the above apps are taking 2 minutes to open that
document, though, 
there's something rather fishy going on =)
