Betreff: Re: delta-syncrepl and mirrormode problem (2.4.29)
I wanted to add, that one database is empty when I start and the other has
only some data. But with master/slave this is no problem, so I think it
should also work for master/master, doesn't it?
I retried with a patched version with these patches:
<
http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=patch;h=8e7af6331ec2d0edaeb203b1c52d4016bc2bbcbf

Unfortunately the problem still persists.
Could at least anyone confirm that the configuration is correct?
Then I can at last stop searching for a error I possibly did and accept
that OpenLDAP with Master/Master (delta-syncrepl) for Windows simply does
not work.
Best regards,
Frank

Hi,
I want to use delta-syncrepl replication with 2 masters.
But each slapd-process permanently needs about 25 % CPU usage without
any
traffic on it.
The log looks endless like this:

I did my test on 2 Windows PCs and OpenLDAP 2.4.29 with Berkeley 5.1 .
Thanks for any hints,
