[CALUG] Slapd starts up slowly

[Joe Tseng]

Amahi for F14 will be released sometime this week; I am definitely planning
on doing that upgrade.  They said they did not consider releasing for CentOS
5.x due to their platform dependencies for Ruby on Rails.

As for the size of my database/schema it shouldn't be very large as it
currently is me, the wife and son and three workstation nodes.  What I don't
understand is it JUST started behaving like this, and I haven't really added
anything new to LDAP once it was up and running.

I also noticed I had to redo my /etc/ldap.conf; it was replaced by some
default file.  Although I restored to what it was previously it made no
difference in speed.

It is not uncommon for LDAP services with a sizable DB and/or extensive
schema to take several moments to shutdown and restart.  The alleged
circular reference could be the LDAP init service seeing if the service is
still up or down, when it's trying to down and up, respectively.

How big is your DB and/or schema?

P.S.  Fedora 12 is no longer maintained as of December.  Have you considered
either an annual lifecycle approach for Fedora, or possibly an Enterprise
Linux release (commercial or unsupported rebuilds) with a longer lifecycle?
Does Amahi run on Red Hat Enterprise Linux release 6 (RHEL6), which just
came last November?

- Rebuild (no release 6 yet, likely soon):  http://www.centos.org/ For home
users and professionals, there is a $99/year Red Hat "developer" 
subscription (includes all platform and middleware products):

I recently set up an Amahi-based file server using  F12 and I configured it
to run as a PDC with Samba and OpenLDAP.  It had  been running very smoothly
until just tonight when I discovered when I tried to  restart the slapd
service it would just sit there for a few minutes.  After  it did start I
looked in /var/log/messages to see if I could glean some clues;  it seems as
part of "service slapd start" the system would request information  from
slapd in order 
to restart slapd.  Seems pretty circular to me...   I did not note any type
of 
success message when slapd finally did wake up from  suspended animation.
 
So my $64,000 questions are what is causing this  and why is it rearing its
head 

now after running flawlessly for almost 2  months?
 
Thanks for clueing me in...
