关于在1.7.2集群版中训练hetero_secure_boost的一个问题

[Sword-CS]

Describe the bug 在1.7.2集群中，按照如下四种配置去训练hetero_secure_boost： 样本量 特征量 样本量 特征量

1. guest: 15W 2000 host: 15W 2000
2. guest: 15W 3000 host: 15W 3000
3. guest 25W 1000 host: 25W 4000
4. guest 25W 10 host: 25W 5000

前面的各个组件（数据读取、转换、求交）都成功了，但是在模型训练时，却总是失败。 logs文件夹下会生成一个fate_flow_detect.log文件，如下图所示： 提示模型训练的某个子进程不存在，导致训练任务被杀掉了，具体内容如下： [INFO] [2022-08-09 15:21:50,924] [202208091448139457690] [20:140055652448000] - [detector.detect_r unning_task] [line:57]: task 202208091448139457690_hetero_secure_boost_0 1 on guest 9999 with runn ing process 25545 does not exist [INFO] [2022-08-09 15:21:53,932] [202208091448139457690] [20:140055652448000] - [detector.detect_r unning_task] [line:65]: task 202208091448139457690_hetero_secure_boost_0 1 on guest 9999 party sta tus has changed to failed, may be stopped by task_controller.stop_task, pass stop job again

由于以上原因，总是导致job失败，但我不知道是因为什么导致模型训练的子进程没掉了。 而在这之前，我对guest和host分别以25W10维和25W3000维、15W1000维和15W1000维的数据去训练模型，运行就没问题。

综上所述，当我提高特征量去跑hetero_secure_boost时，总是会由于子进程不存在而失败，请教一下可能的原因是什么？ To Reproduce Steps to reproduce the behavior:
