Quanah,

Thank you for the suggestion to move to delta-syncrepl MMR. Unfortunately, I am having problems setting this up properly. After reading through some documentation, I thought it would be simple but when I bring up slapd on my two servers, they both start using around 100% CPU and in the debug output the two servers are constantly looping through all of the objects in my DIT and saying that the objects have not changed:

Am I configuring something incorrectly?

To refresh your memory, I am running 2.4.39-8. I have two servers (server1 and server2) that I want to setup in delta-syncrepl MMR MirrorMode.

Hi Kevin,

I stopped using the deprecated slapd.conf format years ago, as it's prone to misuse and incorrect setup. Your supplied config is an example of why it's a bad idea to use slapd.conf (For example, you have serverID under the database section, when it's a global option, etc). I'd strongly advise you to switch to using cn=config so that you can have an actual validated configuration. It also makes troubleshooting a lot easier to do.

Aside from that, your log simply shows the server comparing each entry between the two servers... Sounds like they didn't start out believing they were in sync and are trying to get there.

Here's an example of my config, using cn=config (slapcat export) minus the schema:
