标题: Loadrunner 场景运行时提示Exception ACCESS_VIOLATION received.

进行下载的压力测试，文件大小为30M。
虚拟用户为10个时没有问题，100个时运行出错，提示如下：
Action.c(52): Error: C interpreter run time error: Action.c (52):  Error -- memory violation : Exception ACCESS_VIOLATION received.

感觉要调整：  web_set_max_html_param_len("XXXX");  这个XXXX单位是多少？字节吗？  如果是字节，为什么设置为1024，30M文件也下载保存成功？

具体脚本如下：

Action()
{
int returncode;
//文件大小
long flen;
long filesize;
//响应数据内容大小
long filedes;
//下载文件时间
long timer;
long stimer;
//下载文件时间
long rate;
//文件名
char filename[1024];

// web_url("csim",
// "URL=http://192.168.1.1:8080/csim",
// "Resource=0",
// "RecContentType=text/html",
// "Referer=",
// "Snapshot=t12.inf",
// "Mode=HTML",
// LAST);
//
// lr_think_time(4);
//
// web_submit_form("login",
// "Snapshot=t13.inf",
// ITEMDATA,
// "Name=uname", "Value={username}", ENDITEM,
// "Name=password", "Value=098f6bcd4621d373cade4e832627b4f6", ENDITEM,
//    LAST);
//
// lr_think_time(5);

      //设置页面接受最大的字节数，该设置应大于下载文件的大小
web_set_max_html_param_len("1024");

//将响应信息存放到fcontent变量
web_reg_save_param("fcontent",
      "LB=",
      "RB=",
      "Ord=1",
      "Search=Body",
      LAST);
lr_rendezvous("下载");

lr_start_transaction("test");

if(returncode = 200)

   lr_set_transaction("Download", stimer, LR_PASS);

else

   {lr_set_transaction("Download", stimer, LR_FAIL);

         return -1;}

//生成随机的文件名称，便于并发
strcpy(filename,"d:\\test\\Video_VuserID");

运行的时候先看下本机内存占用是多少，在改程序
