### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### Search before asking - [x] I have searched in the [issues](https://github.com/apache/kyuubi/issues?q=is%3Aissue) and found no similar issues. ### Describe the bug When attempting to connect to the Kyuubi server, the connection intermittently fails due to a socket timeout issue. Logs indicate that the connection to the ZooKeeper server is lost and then re-established. However, this results in disruptions when attempting to interact with Kyuubi, causing instability in client connections. ### Affects Version(s) master ### Kyuubi Server Log Output ```logtalk [ { "timeMillis": 1743312078141, "timestamp": "2025-03-30T05:21:18.141+0000", "thread": "main-SendThread(zookeeper.nprod-green-dev-zookeeper.svc.cluster.local:2181)", "threadId": 20, "threadPriority": 5, "level": "INFO", "loggerName": "org.apache.kyuubi.shaded.zookeeper.ClientCnxn", "message": "Unable to read additional data from server sessionid 0x2007639831c0000, likely server has closed socket, closing socket connection and attempting reconnect", "contextMap": {}, "endOfBatch": false, "loggerFqcn": "org.apache.logging.slf4j.Log4jLogger" }, { "timeMillis": 1743312080239, "timestamp": "2025-03-30T05:21:20.239+0000", "thread": "main-SendThread(zookeeper.nprod-green-dev-zookeeper.svc.cluster.local:2181)", "threadId": 20, "threadPriority": 5, "level": "INFO", "loggerName": "org.apache.kyuubi.shaded.zookeeper.ClientCnxn", "message": "Opening socket connection to server zookeeper.nprod-green-dev-zookeeper.svc.cluster.local/10.97.33.246:2181.
