[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?

### Anything else?

_No response_

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Inizia in SessionPool.java, in getSession (riga 363) e insertAlignedTablets (righe 646 e 681), quindi riproduci il carico di lavoro segnalato con un cluster a tre nodi, maxSize=8 e circa 40 QPS. Traccia il motivo per cui l’acquisizione della connessione va in timeout dopo diverse centinaia di inserts; il lavoro è completato quando insertAlignedTablets termina correttamente con questo carico di lavoro senza il timeout segnalato.

Scritto dal modello di indicizzazione a partire dal testo della issue.
