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>

the best way to monitor for these

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>
