“当1分钟load进程超过24个的时候就会重启”<br>
看了下原文是 the load average exceeds 24 in any 1-minute span.<br>
翻译成“一分钟内cpu负载超过24”应该会好些<br>
这里有load average 的介绍 <a href="http://blog.scoutapp.com/articles/2009/07/31/understanding-load-averages" target="_blank" style="border: 0px none rgb(51, 102, 153); color: rgb(51, 102, 153); display: inline; font-style: normal; font-variant: normal; font-weight: normal; font-size: 14px; line-height: 21px; font-family: Tahoma, Helvetica, SimSun, sans-serif; margin: 0px; outline: rgb(51, 102, 153) none 0px; padding: 0px; text-decoration: underline; word-wrap: break-word;">http://blog.scoutapp.com/article ... nding-load-averages</a><br>
查看load average 可用 uptime 或者top命令<br>
10:59:58 up 3 min, 1 user, load average: 0.25, 0.41, 0.20<br>
0.25, 0.41, 0.20 这三个值分别是 1分钟、5分钟、15分钟内cpu的平均负载<br>
