RE: openldap openldap-2.0.25 using 700M of RAM

["Howard Chu" <hyc@highlandsun.com>]

You're on Linux, you're not dealing with separate processes here.
There is only one process, with a resident size of 21M in your case, with
multiple
threads. You don't add the memory usage "collectively", they are all
executing
from a single address space. Notice that all of their memory figures are
identical...
