This error indicates that there was an issue with processing a message that was expected to be processed exactly once, which is crucial for maintaining data integrity and consistency.

  Configuration Issues: Incorrect configuration settings in the message processing framework or in the integration setup can lead to this error.
  Data Integrity Issues: If the data being processed is inconsistent or violates business rules, it may trigger this error.
  System Performance: High load on the system can lead to delays and timeouts, causing messages to be retried unnecessarily.
