Error in /var/log/univention/listener.log

I have installed guacamole on the DC-Backup. The installation shows some errors and I have removed guacamole. Know I have the following error-Message in the log-File /var/log/univention/listener.log on the Master:
22.04.20 18:54:30.396 LISTENER ( ERROR ) : notifier.c:129:notifier_wait_id_result LDAP failed No such object (32): id:1575
The ID 1575 is not in the file /var/lib/univention-ldap/notify/transaction.
In this File I find the ID 1573 and 1578.
Have anyone a hint for me? :slight_smile:Thanks!
