<div><font face="Calibri,sans-serif" style="color: rgb(0, 0, 0); font-size: 14px;">Thanks for the information. I’m actually running 6.5 not 6.6. The latest version I’m seeing f</font>or 6.5 is 1.2.11.15-34.el6_5. Is that version for 6.5 about the same (in
terms of bug fixes) as 1.2.11.15-47 in 6.6? If so, I’ll check out 1.2.11.15-34 in 6.5. Otherwise, I’ll upgrade to 6.6 first. Appreciate the help.</div>

<br>
Yes and no. 1.2.11.15 was the starting point for EL6. However, many, many features and fixes have been backported from later versions into 1.2.11.15-47 in EL 6.6.<br>

<br>
Has that issue been fixed in 1.2.11.15-47 in EL 6.6? I know a lot of 389 community members running on EL6 were using fedorapeople/copr repos because they could not wait until those fixes/features were available in EL 6.6. Now that EL 6.6 is out, I encourage
you (and anyone else in this situation) to stop using fedorapeople/copr builds and instead use 1.2.11.15-47 in EL 6.6.<br>

You can also monitor the errors logs.<br>

I would strongly encourage you to use the version provided with EL 6.6, which is 389-ds-base-1.2.11.15-47. It looks like you are using a build from the old rmeggins repo or the newer copr repo. These are really only for those users who needed critical fixes
or features not yet in the "supported" EL6.6 version. I don't know if that will fix your problem, but it will make it a lot easier to support.<br>

<div>I simply restarted that directory and then the update succeeded. However, when the update went to the other 5 servers, they failed in the same way and the same error was logged in their log files. But the update wasn’t retried. It was just skipped and
future updates via replication succeeded on those 5 servers.</div>

</div>
<div>My second question is, what’s the best way to monitor for these types of replication errors? In this case, nsds5replicaLastUpdateStatus did not indicate a problem. If I had not been looking at the error file on those 5 hosts, I’m wondering how I would
have known that a delete failed to replicate to them. If the answer is to just have something monitoring the error log files, are there specific search strings to look for to separate out updates that have failed and won’t be retried from other errors (e.g.
temporary connection issues)? Just curious if there is a best practice here.</div>
