我在 8 核 64 位的 linux（red hat vm）上安装了 netty。

limit :
cputime      unlimited
filesize     unlimited
datasize     unlimited
stacksize    10240 kbytes
coredumpsize 0 kbytes
memoryuse    unlimited
vmemoryuse   unlimited
descriptors  65535
memorylocked 64 kbytes
maxproc      8192

在 windows xp 中，我运行调用 5000 个 http post 请求的 Jmeter。我每次只能处理 3000~ 个请求，永远不会超过它。如果我检查失败的 jmeter 请求，我会收到此异常：

在网络方面，我没有看到任何错误或异常，它只是站着听。如果我做 ：

netstat -a | grep ESTABLISHED | grep 8881 | wc -l

我看到 50 个打开的连接（我认为）。当我关闭 netty 并再次运行 netstate 时，我打开了 0 个连接。但我不知道这是否相关。我的问题是如何检测我不能做更多请求的方式？

解决方案 ！
将客户端移至 Linux ！
