+++ This bug was initially created as a clone of Bug #38754 +++

Ticket#2015052021000181

univention-join contains two loops to stop the notifier and the listener. Both may run infinitely if the services don't stop for some reason (e.g listener in initialization phase).

I think it should be okay to forcefully stop both services if they don't respond to 1+n "stop-tries". There is nothing that could break because listener cache and status as well as the LDAP DB is removed during join.

We should improve the behaviour via erratum. It occurs often in various scenarios and this would be the generix "fix".

I rejoined a slave after stopping the listener and manually extended /var/lib/univention-ldap/notify/transaction

OK - forcefully kill notifier and listener
