现象:开机或登录,UserEventAgent占用CPU 100%,内存占用每秒疯狂增长,曾经达到过20G被Force Quit
可重现:100%重现
解决方法:开机执行如下shell脚本,并输入密码
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
以下是相同案例,但通过禁止某些系统启动项 来解决的
