**【环境信息】**
硬件信息

- 提供跟硬件相关的信息，如架构、cpu和内存规格等
- 虚拟机场景，额外补充宿主机os版本类型

软件信息

- 跟缺陷所属软件相关的其它软件版本信息（如软件包构建失败由gcc引起，请填写gcc的版本号）

网络信息

- 如果有特殊组网，请提供网络拓扑信息以及网络数据走向

**【问题复现步骤】：请描述具体的操作步骤**
```
场景1：
[root@openEuler test_rpm]# systemctl start sentryCollector
[root@openEuler test_rpm]# systemctl status sentryCollector
[root@openEuler test_rpm]# tail -f /var/log/sysSentry/collector.log

场景2：
[root@openEuler test_rpm]# systemctl stop sentryCollector
[root@openEuler test_rpm]# systemctl status sentryCollector
[root@openEuler test_rpm]# tail -f /var/log/sysSentry/collector.log
```

**【实际结果】**，请描述出问题的结果和影响
```
结果1：打印了 "kernel lock-free collection"
● sentryCollector.service - Collection module added for sysSentry and kernel lock-free collection
   Loaded: loaded (/usr/lib/systemd/system/sentryCollector.service; disabled; vendor preset: disabled)
   Active: active (running) since Tue 2024-10-08 10:53:56 CST; 7s ago

Oct 08 10:53:56 openEuler systemd[1]: Started Collection module added for sysSentry and kernel lock-free collection.
--------------------------------------
打印了多次ERROR：

结果2：打印了两遍ebpf collector thread exit，一个是exit，一个是exits

2024-10-08 11:00:28,000 - INFO - [collect_io.py:441] - ebpf collector thread exits
-------------------------------
执行systemctl stop sentryCollector后查看服务状态，有异常调用栈打印
[root@openEuler test_rpm]# systemctl status sentryCollector

```

**【期望结果】**，请描述出期望的结果和影响
```
预期1：不会打印 "kernel lock-free collection"；既然是非无锁内核，不再需要打印所有磁盘都没有blk_io_hierarchy ，打印1次就够了, 且日志级别不应该是ERROR
预期2：打印1次就够了；不会有异常调动栈打印
```
