Symptoms:

OL8.10 instance on ExaDB-D (Exadata Database Service on Dedicated Infrastructure) can observe RDS reconnections taking a very long time to complete (e.g. can be as long as 16 hours to reestablish).

This issue happened after image upgrade from 23.1.22.0.0.250119 to 25.1.2.0.0.250213.1.

Here is an example.

An RDS connection reset happened and it subsequently triggered a reconnection.
