LoadRunner脚本问题

　　录制了一段loadrunner测试脚本，但是回放的时候总是跑不通，总是报错12002。报错的位置是在请求ajax文件的web_custom_request函数处。    

报错的代码位置：

         

 web_custom_request("ReverseAjax.dwr", 
        "URL=http://10.133.210.49:9011/khyx/dwr/call/plainpoll/ReverseAjax.dwr", 
        "Method=POST", 
        "Resource=0", 
        "RecContentType=text/javascript", 
        "Referer=http://10.133.210.49:9011/khyx/um/umtmenu/prepareAll.do", 
        "Snapshot=t70.inf", 
        "Mode=HTTP", 
        "EncType=text/plain", 
        "Body=windowName=main\ncallCount=1\nbatchId=2\ninstanceId=0\npage=%2Fkhyx%2Fum%2Fumtmenu%2FprepareAll.do\nscriptSessionId=3vg0y$s*wR9Y3tSH81LnfXFslBk/yLFslBk-iLQy*g2fy\npartialResponse=0\n", 
        LAST);

报错内容：

Action.c(603): Error -27492: "HttpSendRequest" failed, Windows error code=12002 and retry limit (0) exceeded for URL="http://10.133.210.49:9011/khyx/dwr/call/plainpoll/ReverseAjax.dwr" [MsgId: MERR-27492]

录制的时候用的url-based 方式，reverseAjax使用的comet模式。有没牛人遇到过这个问题，求高手
