<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>
<br>
