I have a log stream task to snowflake:

some time rarely happen below warning, I couldnt find the log indicate what's the root cause for it. it is potentially lost some data if we dont know the root cause.

warning is:

Hello @JimXu ,

Thanks for reaching out!

Not very sure what's the source database and Replicate version, there are 2 similar articles:

Qlik Replicate reports changes are not being captured error

Please check and let me know if you need any additional assistance.

Good luck,

John.

Hi @JimXu ,

Thank you for reaching out to the Qlik community with your inquiry!

Regarding the "changes are not being captured" warning, we have identified two potential causes:

Valid Scenario: This warning may occur when the parent/log stream tasks fail to receive data from the source.
Error Scenario: In this situation, the parent/log stream task encounters an issue but continues to run without generating an error. If you encounter this warning on the replication task, we recommend examining the staging task for any potential errors during the same time frame. Please refer to the below community post : https://community.qlik.com/t5/Official-Support-Articles/Qlik-Replicate-reports-changes-are-not-being-captured-error/ta-p/1901483

To investigate the issue further, we suggest checking the parent/log task on the console to review the latest time that events came for the tables related to the child task (the one with the warning).

For more accurate root cause analysis, we would require access to your task logs. To facilitate a thorough investigation, we highly recommend opening a support case. Our team will be more than happy to assist you in resolving the issue promptly and efficiently.

Please don't hesitate to contact us if you have any further questions or require additional assistance. We value your engagement with the Qlik community and are committed to providing the best support possible.

Thank you for your cooperation.

Best regards,
