of course. That's what I was explaining in the 2 previous posts.

In the 1st post, I said I've changed this value to 4096, recompiled
openldap & still seems to have the same limits. (that is 1024 open
files)

So the question is (& it's probably not openLDAP related at all now) is
changing NR_OPEN form 1024 to 4096 supposed to work and raise 
the limit to 4096 open file/socket per process ??

Or do I have to change others include/library ???


Stricly openLDAP related issue now : IF we can't pass this 1024 fd
barrier, is it possible to use a forking model in that case ?? If I
understand correctly, threads shares all ressources (and so, the 1024
limit is for the whole set of threads) - forks, instead are real
processes ... and don't suffer from the same problem... 
But I doubt there is such a mecanism in openldap 2.0.7 (and I imagine it
will complexify code a little...)
