Hello, we have recently migrated our MySQL instances from a legacy EC2 installation to Aurora MySQL to improve the application performances leveraging the read replicas. Since the go live, we've noticed that randomly, the reader instances restart with the following message in the "Recent Events" section:
Attempting to restart the database with zero downtime.
The error logs of the interested instances are empty, all the metrics look okay, and we don't see any pattern that may cause the restart. Only the reader instances have this issue. The database instance type used is the r6g.2xl. The database engine used is Aurora MySQL 3.02.3 (compatible with MySQL 8.0.23)
Does anyone have any ideas here?
