	In the man file for slad.conf, I searched for checkpoint, no mention of 
it ... Now googling for it ... Found ... 
http://www.zytrax.com/books/ldap/ch6/bdb.html

	I would like to try and stick with what FC ship, playing with upgraded 
version, because they should move to that ... But I'm also thinking, 
they might not focus much on OpenLDAP any more, because of 
FedorDirectory Server 
(http://directory.fedora.redhat.com/wiki/Main_Page), which RedHat just 
bought and opensorced.

	I don't seeing anything like that, so I don't think so ... I will look 
into this.

	When the DB get's corrupt, no need to stop slap, have delete the 
default DB and my DB and restart from scratch and slapadd in my current 
DB ... with is only 1000 entries.

	Will a slapd_db_recover not lose any data?

	At the slave sites, I have rsync over what is there, it's quick because 
most of the data is fine, just something is not ...

	I'm really waiting for FC to dump there OpenLDAP packages to 2.3.11 ... 
Messed with sync-repl for test in 2.2, but it's a little buggy ...

	What do you mean, get a better init script ... I think the one in FC4 
is not bad ... Given me a bit of trouble when I wanted to funny thing 
like use included for my conf files so not to have to duplicate too much ...

	Taken a look, where is the srpm?  I can download that and compile a 
package to play with on a test system.

	I can't seem to find a pattern, it's not like we doing allot of updates 
or something ... I see somebody in the list asking if it's because of 
using different LDAP clients and browsers, but I can't see how that 
would be a problem.

	So, I don't really want to waste your time by setting up a chroot 
system, I would like to find what is causing this ... Thanks.

	I have added the the checkpoint options and put the logs way up, hoping 
I will see something.

	Thanks again.
