Hi Frank,
keep alive entry was introduced https://fedorahosted.org/389/ticket/48266
the ADD failed but does the entry exists on the re-initialized replica ?
It is looking like it was created during total init, so its replicaition
(ADD) may fail because the entry already exists.
thanks

Hi Guys,
I got a replication issue with the 389 ds running at centos 6.7 and the
following 389 pkgs installed:

I'm running a multimaster configuration based on two directory servers (ds1,
ds2)
When the replication is initiated at ds1 (replication from ds1 to ds2,
nsds5BeginReplicaRefresh set to 'start') , I find these entries in the error
log of ds1:

I was wondering about :

Does someone have a glue what the cn=repl keep alive 1,dc=example,dc=org is
for and what causes the problem here?
thank you very much,
