Does it definitely replicate a few changes correctly before the problem
starts? It reminds me of a problem that used to occur with an earlier
6.21 release, but in that case the first change would not be replicated
(changelog empty with no anchor at the head of the list), and the second
would produce the error you're seeing.
I don't think it'd help diagnosing the problem beyond noting that the
change identified by that CSN really is missing, but if you're
interested you can inspect the changelog running the dbscan tool on the
<instance root>/changelogdb/<replica name>.db4 file. You should have as
many .db4 files are you have replicas. You can also make the server
dump it using the CL2LDIF task (see the template-cl-dump.pl script,
requires perldap).

A few months ago, I had a machine die suddenly when the power cord was
tripped over. (Oops!) After that, I had some replication issues that
I solved with the help of this list. Before long, they came back, and
back, and back. Basically, I get a bunch of messages like this in the
error logs:
[22/Dec/2006:09:26:08 -0600] agmt="cn="Replication to
zeppo.nebrwesleyan.edu (o=pab)"" (zeppo:389) - Can't locate CSN
458acc0e000000020000 in the changelog (DBrc=-30990). The consumer may
need to be reinitialized.
[22/Dec/2006:09:31:09 -0600] agmt="cn="Replication to
chico.nebrwesleyan.edu (o=pab)"" (chico:389) - Can't locate CSN
458acc0e000000020000 in the changelog (DBrc=-30990). The consumer may
need to be reinitialized.
I get similar messages on every host in the 4-way MMR group. Each
machine only complains about one CSN, but they're different CSNs on
each machine.
This morning, I took down all of the replication agreements, and
reinitialized every host from one, which I temporarily treated as the
authoritative master. Within minutes, these messages were appearing
again.
Does anyone have any ideas how to solve this once and for all? I've
rebuilt my replication agreements countless times, and nothing seems
to get them in sync. Any and all ideas are welcome. Thanks.
