Lr运行错误Error: Socket descriptor not found. Hint: the problem might be

在controller中，运行时，报如下错误“Error: Socket descriptor not found.  Hint: the problem might be solved applying the following: (1) Update Run-Time Settings to Run Vuser as a process. (2) Add the following line into mdrv.dat, [lr_socks] section: 'ExtCmdLineConc=-UsingWinInet Yes'.”
解决方法：
1、根据错误提示，在run-time setting中的Miscellaneous项中设置“run vuser as a process”；在安装目录的dat文件夹中查找mdrv.dat，找到[lr_socks]段，在最后添加“ExtCmdLineConc=-UsingWinInet Yes”一句；
2、在选择了expert mode后，选择option->general，选中“ip address allocation per process”；
3、如果仍然报错，在菜单栏中点击Diagnostics->configuration项，将web page diagnostics项disable掉（该路径是在loadrunner11中的位置，若是loadrunner8.0，则在Diagnostics--->Distribution，disable Web Page Diagnostics选项）
