平均负载节节上升，一般而言，负载上2就有问题了。

弱弱的问一下，你的问题可解决了，若是解决，如何解决的，我也碰到这样情况，SENDMAIL每天早上都要手工重启，日志如下：sendmail[779]: rejecting connections on daemon MTA: load average: 29
last message repeated 3 times
last message repeated 3 times
sendmail[18238]: grew WorkList for /var/spool/mqueue to 68000
rejecting connections on daemon MTA: load average: 30
last message repeated 3 times
last message repeated 3 times
sendmail[779]: rejecting connections on daemon MTA: load average: 29
这是日志里面截取的一部分。
