Thank you very much.
I have changed my slapd to OpenLdap 1.2.11.But it can not fix that problem.
If I use slapd with linux threads, slapd dies in several days.If  I use slapd without threads,
slapd often costs 99% CPU too.
Teemu Antti-Poika has post a article about sub-scope searches and performance.
he said,
"Queries using scope BASE or ONE work properly and efficiently
but if I want to restrict the search space using the SUB scope,
the search seems to go through the entire database in a linear 
fashion. With a couple of million entries, this takes time."

I found this problem too.When I restrict the search space using SUB scope,slapd costs 99% CPU at once.

Yes.I try to use slapd with pth 1.3.6.But when I make test,it often failed.I will try again using OpenLdap 1.2.11.
./configure --with-ldbm-api=gdbm --with-threads=pth
