我在尝试在 Mac OS X 10.8.3 上从围攻中运行以下 cmd 时遇到了这个问题。

siege -d1 -c 20 -t2m -i -f -r10 urls.txt

Siege 的输出如下：

** SIEGE 2.74
** Preparing 20 concurrent users for battle.
The server is now under siege...
done.
siege aborted due to excessive socket failure; you
can change the failure threshold in $HOME/.siegerc

You can disable this annoying message by editing
the .siegerc file in your home directory; change
the directive 'show-logfile' to false.

问题可能是您的临时端口用完了。要解决这个问题，要么扩大要使用的端口数量，要么减少端口停留在 TIME_WAIT 中的持续时间，或者两者兼而有之。

展开可用端口：

检查您当前的设置：

$ sudo sysctl net.inet.ip.portrange.hifirst

net.inet.ip.portrange.hifirst: 49152

将其设置为较低以扩展您的窗口：

$ sudo sysctl -w net.inet.ip.portrange.hifirst=32768

net.inet.ip.portrange.hifirst: 49152 -> 32768

（hilast 应该已经达到最大值，65536）

缩短最大分段寿命

$ sudo sysctl -w net.inet.tcp.msl=1000

net.inet.tcp.msl: 15000 -> 1000
