我正在尝试让爬网在SharePoint上运行，但完全爬网永远不会停止，当我停止爬网时，爬网日志就在下面。

Error while crawling LOB contents. ( Error caused by exception:
Microsoft.BusinessData.Infrastructure.BdcException The shim execution failed
unexpectedly - Exception has been thrown by the target of an invocation..:
System.Net.WebException The request failed with HTTP status 404: Not Found. )
我一直在网上搜索并确保文件夹具有正确的权限等
我让搜索的最长时间是100小时
使用：
Sharepoint 2013 Foundation
Server 2008 R2
有没有人以前见过这个或有任何想法尝试并正确地进行此操作？
