報錯信息如下：
Salt request timed out. The master is not responding. You may need to run your command with `--async` in order to bypass the congested event bus. With `--async`, the CLI tool will print the job id (jid) and exit immediately without listening for responses. You can then use `salt-run jobs.lookup_jid` to look up the results of the job in the job cache later.
CPU一直是非常的高，解決方法是通過 strace -p 7161 跟蹤這個pid查出salt再做什么，我這里查出是在lstat一個目錄，目錄異常，經確認后無用，
刪除目錄后解決。
