现象:开机或登陆,UserEventAgent占用CPU 100%,内存占用每秒疯狂增加,曾经达到过20G被Force Quitshell
可重现:100%重现bash
解决方法:开机执行以下shell脚本,并输入密码app
bugpid=`ps -ef |grep UserEventAgent |grep System |awk '{print $2}'` echo 'UserEventAgent (System) pid was '$bugpid sleep 2 sudo kill -9 $bugpid sleep 1 bugpid=`ps -ef |grep UserEventAgent |grep System |awk '{print $2}'` echo 'UserEventAgent (System) pid is '$bugpid
如下是相同案例,但经过禁止某些系统启动项 来解决的ide
