Turning on replication logs would help ( <a class="moz-txt-link-freetext" href="http://www.port389.org/docs/389ds/FAQ/faq.html#troubleshooting">http://www.port389.org/docs/389ds/FAQ/faq.html#troubleshooting</a>). In the sample of the log, there is a failure while ending a replication session. No replication error before ? It is like suddenly server1 was no longer able to reach server2 (dns or network issue ?). thanks thierry <blockquote cite="mid:etPan.546b93a6.327b23c6.16f@Drone-5.appnovation.com" type="cite"> <div> </div> <div> <div id="bloop_sign_1416336143796808960" class="bloop_sign"> <div style="font-family:helvetica,arial;font-size:13px"> Will Sheldon </div> <div style="font-family:helvetica,arial;font-size:13px"> </div> </div> On November 18, 2014 at 8:37:10 AM, <a class="moz-txt-link-abbreviated" href="mailto:dbischof@hrz.uni-kassel.de">dbischof@hrz.uni-kassel.de</a> (<a moz-do-not-send="true" href="mailto:dbischof@hrz.uni-kassel.de">dbischof@hrz.uni-kassel.de</a>) wrote: <blockquote type="cite" class="clean_bq"> <div> <div>Hi, On Fri, 7 Nov 2014, Dmitri Pal wrote: > On 11/07/2014 01:24 AM, Will Sheldon wrote: >> On November 6, 2014 at 10:07:54 PM, Dmitri Pal (<a class="moz-txt-link-abbreviated" href="mailto:dpal@redhat.com">dpal@redhat.com</a> >> <a class="moz-txt-link-rfc2396E" href="mailto:dpal@redhat.com"><mailto:dpal@redhat.com></a>) wrote: >>> On 11/07/2014 12:18 AM, Will Sheldon wrote: >>>> >>>> On the whole we are loving FreeIPA, Many thanks and much respect to >>>> all involved, we’ve had a great 12-18 months hassle free use out of >>>> it - it is a fantastically stable trouble free solution… however now >>>> we’ve run into a small issue we (as mere mortals) are finding it hard >>>> to resolve :-/ >>>> >>>> We upgraded our ipa servers (3.0.0-42) to Centos 6.6. everything >>>> seems to go well, but one server is behaving oddly.

I observe it on my systems, too. Exact same symptoms. ldapsearch with "-Y GSSAPI" works. > Did you find anything in the server2 logs?
