WSA_IO_PENDING 是什么错误？

higkoo

Index.c(7): Error -27740: Overlapped transmission of request to "testserver" for URL "http://testserver:8888/" failed: WSA_IO_PENDING

测试一个网站的并发，150个用户时出现这个提示。

但此时我用IE访问，速度是很快的，服务器没有任何问题。

反而是负载机器CPU满载，请知道的朋友吗？

150个用户按线程生成的话记得好像是每个500,600k的样子，不知道是不是测试机资源耗尽产生的问题，减少一点看看

负载机器CPU满载，说明你负载机器负担太重了，减少用户或者增加load geneator试试。

Overlapped transmission of request to '%1' for URL 'URL' failed.

The transmission of data to the server failed. It could be a network, router, or server problem. The word Overlapped refers to the way LoadRunner sends data in order to get a Web Page Breakdown.

Troubleshooting
Add the following statement to the beginning of the script to disable the breakdown of the "First Buffer" into server and network time: web_set_sockets_option("OVERLAPPED_SEND", "0");
