[Bug] fatal error: OutOfMemory encountered: Java heap space

### Search before asking

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

### Version

1.3.4

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

I have a standalone configuration of IoTDB on a cloud server witrh 2GB of total memory.
I am encountering fatal error due to java heap space several times per day, where datanode seems to stop working.
I have configured MEMORY_SIZE in both confignode and datanode so both values are less than 2G (e.g. 600M and 600M) but this is not working. I am attaching the error log.

[hs_err_pid67335.log](https://github.com/user-attachments/files/20003020/hs_err_pid67335.log)

Any help appreciated.

### What did you expect to see?

Sort out this annoying fatal error which is stopping the service. This did not happen before on version 1.2.x

### What did you see instead?

The service stops, unable to push any data to database

### Anything else?

_No response_

### Are you willing to submit a PR?

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

Comience con el archivo adjunto hs_err_pid67335.log y la configuración de MEMORY_SIZE para ConfigNode y DataNode en IoTDB 1.3.4. Compare el fallo con el comportamiento notificado en 1.2.x y determine por qué el servicio agota el heap de Java a pesar de los límites configurados. Se considera completado cuando se haya identificado la causa y el DataNode ya no se detenga con la configuración standalone indicada.
