Znuny/Znuny LTS is a fork of the ((OTRS)) Community Edition, one of the most flexible web-based ticketing systems used for Customer Service, Help Desk, IT Service Management.
It looks like znuny performs the insert of the ticket_flag key "MentionSeen" twice when viewing a ticket for the first time under certain conditions. This has to happen within a very short time because the entry in the DB and the duplicate entry error message usually appear in the same second or at most with a difference of one second.
Environment
