**For better global communication, Please describe it in English. If you feel the description in English is not clear, then you can append description in Chinese(just for Mandarin(CN)), thx! **
**Describe the bug**
When the master gets a process with more than 100(master.exec.threads - activeCount) sub processes, it will wait permanently.
**To Reproduce**
Steps to reproduce the behavior, for example:
1. Go to 'Define process A, there are 10 common subprocesses, define a process B, there are 10 processes A'
定义流程A，里面有10个普通子流程，定义一个流程B里面有10个子流程A
2. Click on 'run'
点击运行
4. See error at process instance list，process B will wait permanently.
**Expected behavior**
run process B，Keep it running
**Screenshots**
If applicable, add screenshots to help explain your problem.
**Which version of Dolphin Scheduler:**
-version:all
**Additional context**
**Requirement or improvement**
I don't think process B should be directly put into the waiting thread when dividing the main process, otherwise it will never have a chance to run. Maybe when adding a new process, judge the number of subprocesses and give a friendly prompt.
我认为分割主流程时不该直接将process B放入等待线程，否则永远没有机会运行，也许新增流程时判断子流程数量，给出友好提示
