[Freeipa-users] replica_generate_next_csn messages in dirsrv error logs

[John Desantis]

Hello all,

We've been re-using old host names and IP addresses for a new
deployment of nodes, and recently I've been seeing the messages pasted
below in the slapd-DC.DC.DC "error" log on our nodes.

They seem to only occur when updating DNS entries, whether on the
console or via the GUI (tail -f'ing the log).

A search in this mailing-list returns nothing, but a message is found
on the 389-ds list [1];  it seems to suggest that the messages aren't
fatal and are purely informational, yet if they are occurring
constantly that there could be a problem with the replication
algorithm and/or deployment.

We're using ipa-server 3.0.0-47 and 389-ds 1.2.11.15-60.  Nothing has
changed on the deployment side of things, and I don't recall seeing
this message before.

I'm wondering if it's safe to disregard these messages due to the
re-use of the entries, or if something else should be looked into.

Thank you,
John DeSantis
