[Bug] 使用SessionPool连接集群，insertAlignedTablets接口报错：获取session超时

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.

### Version

0.13.3

### Describe the bug and provide the minimal reproduce step

1. SessionPool连接三节点IoTDB集群：

` @Bean

public SessionPool getSessionPool() {

SessionPool sessionPool = new SessionPool.Builder()

.nodeUrls(clusterNodes)

.user(account.getUsername())

.password(account.getPassword())

.fetchSize(fetchSize)

.maxSize(maxSize)

.build();

return sessionPool;

} `
fetchSize=10000
maxSize=8

2. 通过设备遥测信息上报，触发时序数据写入，调用方法：insertAlignedTablets
3. 当QPS大约40的时候，前几百条插入正常，然后报错：
timeout to get a connection from null:-1

### What did you expect to see?

success

### What did you see instead?

Bắt đầu trong SessionPool.java tại getSession (dòng 363) và insertAlignedTablets (các dòng 646 và 681), sau đó tái hiện workload đã được báo cáo với một cluster ba node, maxSize=8 và QPS khoảng 40. Theo dõi lý do việc thu nhận kết nối bị timeout sau vài trăm inserts; được xem là hoàn tất khi insertAlignedTablets hoàn tất thành công dưới workload này mà không có timeout đã được báo cáo.
