![输入图片说明](https://images.gitee.com/uploads/images/2022/0301/193414_3446c19e_5588484.png "屏幕截图.png")

如果有特殊组网，请提供网络拓扑图
【问题复现步骤】
具体操作步骤
/usr/bin/etmemd -s test_socket -l 0 &
/usr/bin/etmem obj add -f config_project.file -s test_socket
/usr/bin/etmem obj add -f config_slide_engine.file -s test_socket
/usr/bin/etmem obj add -f config_slide_task.file -s test_socket
/usr/bin/etmem project start -s test_socket
出现概率(是否必现，概率性错误)
必现
