### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened After database out of service for longer than session timeout time, client heartbeat will never be updated. ### What you expected to happen If the database recover after session timeout time, client heatbeat should be updated again. ### How to reproduce 1. Shutdown database server for a session timeout time. 2. Start database server. 3. If the scheduled task `purgeInvalidJdbcRegistryMetadata` purge the client heart beat before the heart beat be updated. After the client heart beat being deleted, the heart beat will never be updated by that client ID. ### Anything else _No response_ ### Version dev ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
