# Duplicate messages being sent If you are seeing duplicate messages being sent by Unifi, then there are two things you should check: * Check for duplicate Unifi trigger business rules on your table. This is usually seen in domain separated instances where a trigger rule has been updated in a different domain and therefor inserted a new rule, causing Unifi to fire twice. * You're performing a double update on the record being integrated. It's surprising how often this happens, you just don't see it until Unifi fires twice. Check the history of the record being integrated, are there two updates at the same time? This usually happens when a before rule inserts a record in another table, and that table then updates the initial record, creating a double update i.e. new incident saved with a CI, before rule on incident inserts a new Task CI record for the added CI, after rule on Task CI adds a work note to the incident causing a double update. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
