RDS Blue-green lost packets after switchover

0

I’m encountering a strange issue. We migrated to MySQL 5.7 using blue-green and it went smoothly. Old blue no longer receives any updates. However, when I stop old blue in preparation for deleting it, my apps start generating intermittent MySQL errors complaining of no packet received for n milliseconds. N is frequently a very large number. I have restarted old blue but I need to delete it soon. Has anyone encountered this issue?

If you are using the DNS endpoint for your instance it now points only to the new (green) environment. I do not know the error you are reporting but you can confirm that there are no lingering connections on the blue-old environment by looking at the connection list.
