Hi zhangpanting, welcome to the openEuler Community.

怀疑是kernel、kernel-devel包不配套导致的
uname -r看一下内核版本
rpm -qa |grep kernel看一下内核相关包的版本
@zhangpanting

@zhangpanting 请确认下环境

@swf504

使用rc1的包没有出现这个情况

服务日志输出：

@zhangpanting

用新安装的rc2 机器验证，启动服务后有下面报错
、

操作流程：


@swf504

执行 dnf install -y kernel-devel systemtap*
ystemctl start stap-exporter.service
systemctl status stap-exporter.service
systemctl stop stap-exporter.service
systemctl status stap-exporter.service
查询状态有个报错信息


@langfei

该问题确认为非问题，以上报错原因是先执行systemctl start stap-exporter.service后，stap-exporter服务正在编译ko阶段（status命令可以看到还在pass3），如下图：

若此时再去执行systemctl stop stap-exporter.service命令，又会强制打断编译ko流程，所以出现编译报错如下：

signal: 15 即表示进程被中断。

验证如下：
若start命令后等待一段时间后，再去stop，就不会出现报错。

服务启动需要时间，需要等待成功后再停止服务

等到ko 编译完成后再执行stop 没有报错
