And if it is the case then maybe it is worth implementing the same sort of "dike" for incremental replication? Though it is clear that when the log buffering is disabled,the problem appears later during the initialization (7403 entries with log buffering and 26798 without). The two servers are ldap-edev and ldap-model, nsslapd-db-checkpoint-interval is 5. I will look at them. http://supercgis.com/replication-error/replication-error-acquiring-replica-duplicate-replica-id-detected.html
The optimal values can be continuously computed by the RA by monitoring how fast the consumer consums the sent entries/updates. A parse error temporarily prevented replication from continuing. 401 Replication session failed, consumer replica needs to be initialized Solution: The database on the consumer has not been initialized. Will retry later. thread 2 (repl5_tot_result_threadmain) is trying to read the result from model with conn_read_result_ex, but it cannot acquire the lock (conn->lock) and sitting there; . https://lists.fedoraproject.org/pipermail/389-users/2010-March/011183.html
If you look at the original mail (https://lists.fedoraproject.org/pipermail/389-users/2014-November/017601.html), 陳含林 (laneovcc at gmail.com) had only about 5000 entries and it stuck about 1500. comment:5 Changed 2 years ago by pj101 If you mean setting agreement timeout smaller for each replica: with 60s for both agreements [06/Nov/2014:20:42:20 +0100] NSMMReplicationPlugin - multimaster_be_state_change: replica dc=id,dc=polytechnique,dc=edu is going Correct?

Fix the replication agreement. 4 Replication error acquiring replica: decoding error Solution: A protocol error occurred. 401 Incremental update session stopped: Could not parse update vector Solution: Replication is proceeding normally.

There's a possibility that your replication user account's password expired. >> 3. Ok, I have created a new Supplier Bind DN as: cn=replication manager,cn=config on consumer C as directed in the documentation.

This read-only attribute shows the status of the latest update of the replica. have a peek at these guys the choice of the "lag" of 1000 entries is rather arbitrary/empirical (as well as 2 seconds of sleep). So probably the setting could differs. I had followed step #6 in thedocumentation URL too literally, this is what I had before:cn=replication manager,ou=people,dc=example,dc=comThanks for helping me sort it out!
After replication is reestablished the systems are set up to "Always keep directories in sync". I was unable to reproduce it without any encryption (be it SSL/TLS or Kerberos). The stack traces are attached: before the replication total update started - stacktrace.06-Nov-2014_12h47*.txt after the replication is stuck (all the other traces) The same initial total update using replication agreement with http://supercgis.com/replication-error/replication-error-acquiring-replica-replica-busy.html the sending thread holding lock and pushing a great deal of entries thus overflowing the consumer) may happen during a regular incremental sync?
I had similar replica timeouts when i made a lot of modifications during a short time on source server (like adding an attribute to each ldap entry, for example). Fix the replication agreement. -1 Incremental update has failed and requires a total update Solution: Reinitialize the replica. Good luck - David 2012/3/21 Herb Burnswell
It matches ok for the HEAD or 188.8.131.52.
The rest looks good to me. I assume that upon repairing replication (apparently it has not been working for several years) the systems will all replicate to the most recent information. I've attached the error, access and audit logs in both cases for supplier (ldap-edev) and consumer (ldap-model). Processed 4439 entries in 23 seconds.

You'll have to shutdown the servers, remove all cn=replica entries and their children from cn=config (by editing dse.ldif with a text editor - be sure to make a backup first), then this content I'm not really sure what you can do except to just start over.
Are there detailed descriptions ofthe error codes somewhere?I followed the directions on this page to a T, but it seems somethingis still missing:http://www.redhat.com/docs/manuals/dir-server/8.1/admin/Managing_Replication-Configuring_Single_Master_Replication.html Rich Megginson 2010-03-05 23:21:04 UTC PermalinkRaw Message Post The rest of the configuration is fine. So, what you suggest is to have a huge DB and run the total update, right? Will it be possible you test it in your environment (I am not able to reproduce your exact failure).
That entry is used internally for other purposes. I used 389-ds-base-184.108.40.206.tar.bz2 extracted from git to compile it on CentSO7. I will rework the indentation. I used bak2db with backup files from A.

Let's call >them 'A' and 'B'. I then edited the replication agreement on master A (via the directory server console) to use the new Bind DN credentials. For total update, window/pause are configurable. Just in case here is some more information about the test serveres (VMs): both VMs (vSphere 5.5U2) have 1vCPU, 4Gb RAM, CentOS 7 with latest "yum update" vmtools used are the
A yield should do that - essentially, a sleep with a time of 0. Given the fact that system B has not been running for some time, ideally it would simply replicate to the current data on system A. Total and incremental are not sending the same data and likely the same amount. Maybe these encryption/decryption protocols have their own buffers thus changing the flow dynamics?

Now a similar fix on the incremental update looks quite easy to implement.
