设置Run-time Settings ，network speed ，use bandwidth为 512；
回放脚本没有报错，5个并发运行场景报如下错误：
vuser_init.c(12): 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‘.
1、根据错误提示，在run-time setting中的Miscellaneous项中设置“run vuser as a
process”；
2、...\Program Files
(x86)\HP\LoadRunner\dat\mdrv.dat
查找[lr_socks] 在后面添加“
ExtCmdLineConc=-UsingWinInet Yes
”，如下：
..............[lr_socks]ExtPriorityType=hookWINNT_EXT_LIBS=lr_socks.dllWIN95_EXT_LIBS=lr_socks.dllLINUX_EXT_LIBS=liblr_socks.soSOLARIS_EXT_LIBS=liblr_socks.soHPUX_EXT_LIBS=liblr_socks.slAIX_EXT_LIBS=liblr_socks.soLibCfgFunc=lr_socks_configureExtMessageQueue=0SecurityMode=OnExtCmdLineConc=-UsingWinInet
Yes........
3、如果仍然报错，在菜单栏中点击Diagnostics->configuration项，将web
page diagnostics项改为：Enable （这一招只能说眼不见心不烦），我觉得还有更好的解决办法。
