What happened?

Hello guys,

Current Infrastructure:

• AWS RDS mysql 8
• frankenphp with Symfony 6.4
• patch applied for ILDE connection (improvment from [DoctrineBridge] Idle connection listener for long running runtime symfony/symfony#53214.)
• RDS proxy

Application configuration:

• franken worker mode
• PDO persistence for read calls to RDS

Issue:
Every 24 hours, we have some mysql has gone away on the reader rds proxy endpoint
Seems to be a side effect between Franken / pdo persistent option / rds proxy

RDS proxy:
RDS Proxy enforces a maximum life of client connections of 24 hours. This value is not configurable. Configure your pool with a maximum connection life less than 24 hours to avoid unexpected client connection drops.

Anyone has this kind of issue ?
How Can I fix that ?
