We should update the SDB article https://help.univention.com/t/transaction-file-checking/6418 to include the recommendations of https://hutten.knut.univention.de/blog/listener-notifier-details-recovery/#comment-1093 and https://forge.univention.org/bugzilla/show_bug.cgi?id=47344 in particular.
FYI: https://help.univention.com/t/fixing-translog-issues/11613 This article describes problems with pending transactions when the notifier won't start and gives a solution to fix them. I mention this because this article belongs to this complex.
