@glon Thank you very much for your feedback. I tested it locally and did not reproduce your exception. 😪 Through the exception information you provided, I noticed that it may be caused by an unreasonable connection timeout. You can refer to this [article](https://lchml.com/technology/hikari-maxlifetime/) to check your connection timeout configuration. ``` [WARN ] 10:37:36.364 [ShardingSphere-Command-4] com.zaxxer.hikari.pool.PoolBase - HikariPool-1 - Failed to validate connection com.mysql.jdbc.JDBC4Connection@3ba54078 (No operations allowed after connection closed.). Possibly consider using a shorter maxLifetime value. ``` -- This is an automated message from the Apache Git Service.
