3 解决过程

3.1 修改注册表

HKEY_LOCAL_MACHINE->SOFTWARE->Crystal Decisions->10.2->Report ApplicationServer->Server>PrintJobLimit为-1或300,1000,测试次数最多可延长至148次

 

重启IIS,测试网站,点击次数为235左右时又出错了(PrintJobLimit设置为-1,0,300,500结果一样)

3.2 系统TEMP目录赋予users操作的权限

3.3 使用BAT文件定时重启IIS

清空C:\Documents and Settings\username\ASPNET\Local Settings\Temp\ 下tmp文件

不是长久之计。

3.4  关闭和释放报表资源

private void Page_Unload(object sender, EventArgs e)
{
ReportDoc.Close();
ReportDoc.Dispose();
}

First, the problem is the AppPool, if you review the task manager you can see w3wp.exe with a high Mem Usage this is because you run many reports at the same time and keep alive for many time, this issue produce the error, because don't have more memory assigned to run more reports, the limit are 75. Review your settings in IIS Manager, indetify you application pool, in the Performace Options set "Shutdown worker proccess..." to 5 or something similar and "Limit the kernel request queue.." to 4000 or something similar. Open the report and see if w3wp.exe close or reduce Mem Usage in the time where you set.

4 总结

应急措施：重启IIS

永久措施：关闭和释放报表资源
