Hi,
I noticed an issue with 389 DS 1.2.7.5, which I have not seen before. Here is what I do: 1. I create a two multi-master setup. 2. I don't perform any changes on the directory. 3. I delete the replica setup on both systems -- everything is fine. 4. I create a two multi-master setup. 5. Perform changes on both systems 6. Modifications get replicated. 7 I delete the replica setup. No I get the following error logs:

Rick,
it seems that the issue does not exist in 1.2.8.2. I just compiled and installed it.
If 1.2.8.2 is stable, I won't bother open a bug for it......

Ok, thanks for confirming. 1.2.8.3 is in Testing now - I'm going to push that to Stable in the next couple of days.
