<div class="moz-cite-prefix">Hi Alexander,<br>
<br>
This is mainly replication logging. Having many instances will
increase the amount of logging especially if you have updates.<br>
To create duplicate you are doing ADD in parallele of the same dn
on differents servers. Do you what creates this ADD load ?<br>
Can you see MODs/DELs ?<br>
<br>
thanks<br>

<p class="MsoNormal"><br>
Most of my tests are on RHEV with RHEL 7.1, I have not seen a
crash of DS.<br>
About the test case, you installed a server+replicas (version
?), then turn on errorlog-level (do you remember what level).<br>
That would slow down the DS instance and fill errors log. <br>
Then you hit extremely frequently a crash. Do you remember
what kind of the load search/mod/add/del ?<br>
