mcs 启动uniproton程序概率性会提示响应超时错误

**【标题描述】mcs 启动uniproton程序概率性会提示响应超时错误 **

**【环境信息】**
软件信息
mcs master分支

**【问题复现步骤】**
1、创建mica create kp920.conf
2、删除kp920程序
mica rm kp920
重复步骤1、2 ，半个小时左右
mica create kp920.conf 提示响应超时

**【实际结果】**，mica 启动uniproton程序提示超时，启动失败
**【其他相关附件信息】**
出现mica create kp920.conf 启动失败时，查看micad进程的函数栈启动情况，程序卡在了rproc_register_notifier 的pthread_cond_wait中
