centos系统服务器打开终端很慢, 并显示 abrt-cli status timedout

表现

1、ssh连接经常失败。
2、登录的时候非常卡。
3、登录成功后，会出现一个提示“abrt-cli status timed out”
4、登录成功后输入命令行卡顿，慢动作。

原因

abrtd.service 服务导致。 这是一个可有可无的功能，管理多用户的。

解决方案

systemctl stop abrtd.service

理论上，命令 abrt-auto-reporting enabled 也可以解决此问题。自行尝试。

如果上述命令还是登录卡顿，则排查是否存在 .lock情况。找到对应进程， kill 掉即可。

[root]# systemctl status abrtd.service
