As in the question here: https://learn.microsoft.com/en-us/answers/questions/5567485/what-is-causing-the-following-log-message-in-serve

However, the answers there are not helping me.

I have 4 PostgreSQL flexible servers, and they ALL log this continuously.

Answer 1

The log message indicating that the background worker "azure_mise_service_worker" exited with exit code 1 suggests that there may be an issue with the Azure Managed Instance Service Environment (MISE) worker process. This could be due to various reasons, such as configuration issues, resource constraints, or problems with the underlying service that the worker is trying to interact with. Continuous logging of this message across multiple PostgreSQL flexible servers may indicate a systemic issue affecting the service or a specific configuration that is not functioning correctly.

To troubleshoot this further, consider the following steps:

Check Resource Utilization: Ensure that your servers have adequate resources (CPU, memory) available.
Review Configuration Settings: Verify that all relevant configuration settings for the PostgreSQL servers are correctly set.
Consult Azure Support: If the issue persists, reaching out to Azure support may provide insights specific to your environment and help resolve the issue.

Since this log message is occurring every second, it may also be beneficial to review any recent changes made to the servers or any updates from Azure that could affect the behavior of the MISE worker.
