1、Jmeter高并发压测时，报错解决参考方案：
java.net.SocketException: Connection reset
或 java.net.BindException: Address already in use:connect
或 java.net SocketTimeoutException: Read timed out
或 java.net.SocketException: No buffer space available (maximum connections reached?): connect
以上几个都是因为压测机为Windows时socket连接为得到释放不够用导致的
解决方案：
新建txt,保存以下脚本修改后缀为reg文件，编辑值如下，保存后双击执行；重启电脑，再次压测即不会出现报错
解析中值为10进制，下方脚本已全转换为16进制
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\]
"MaxUserPort"=dword:fffe
"TcpTimedWaitDelay"=dword:1e
"TcpNumConnections"=dword:fffffe
"MaxFreeTcbs"=dword:7D0
"MaxHashTableSize"=dword:10000
