Description Christoph Wickert 2011-12-02 11:19:59 CET

Bei jedem Herunterfahren meiner UCS Server sehe ich den univention-directory-listener abstürzen. Das Problem tritt reproduzierbar auf verschiedenen Maschinen auf, immer beim Herunterfahren. 

Bei einer Maschine passiert es auch ab und zu im laufenden Betrieb, ich habe noch kein Muster erkennen können. Zusätzlich sehe ich noch univention-config-registry segfaulten:

Vermutlich ein Dumplikat von Bug 15355.

Comment 2 Christoph Wickert 2012-06-05 19:27:00 CEST

Leider bin ich nicht berechtigt, bug 15355 zu sehen.

Stimmt, ich hab das gleiche Problem während ich mit einem DC master arbeite. Auch bei mir tritt reproduzierbar beim reboot folgende Meldung in /var/log/messages auf:

UCS 2.4 is out of maintenance and many UCS components have vastly changed in
later releases. Thus, this issue is now being closed.
