'abrt-cli status' timed out

xshell登录时，非常慢，然后提示

'abrt-cli status' timed out

经过查询发现是因为

 abrtd.service

这个服务引起的。这是一个可有可无的功能，管理多用户的。

• 解决办法 ：

systemctl stop  abrtd.service

但是我第一次使用的时候输入之后就立刻生效，第二次发现并不管用。继续研究
怀疑是锁定了进程。排查：

[root]# systemctl start abrtd.service  
[root]# systemctl status abrtd.service

果然不出所料，进程锁死。杀掉进程，再次关闭。OK。
