LDAP is as stable as anything I've ever used but I have to admit that I
don't use nscd anywhere because I would suspect, that is what is killing
you. I stopped using nscd when I went to LDAP for that reason.

It's not uncommon for my primary LDAP servers to have uptimes of over 9
months and never restarting though Red Hat made a curious choice of
using sleepy-cat 4.3 on RHEL 5 which is totally not recommended by
OpenLDAP developers. http://www.openldap.org/faq/data/cache/44.html

I suppose if you wanted to have a stable LDAP, you would investigate
with the developers of OpenLDAP.
