[Fedora-directory-users] fedora-ds-1.0.3 problem: too many fds open

[Sergey Ivanov]

I saw in ds71cli.pdf two parameters which may could help in this case,
one is nsslapd-maxdescriptors, and other is nsslapd-conntablesize, but
in the example it is called another:
"Example: nsslapd-ntconntablesize: 4093"
on page 55 of this book. What is the correct name for this second parameter?
