I am getting a couple of errors in the Search Administration Crawl Logs. These errors are just coming for only one list within SharePoint. It has about 6000 .xlsm documents but views have been configured so that it meets Microsoft Recommended Practices. The error is as follows "Error in the Site Data Web Service. (The item was deleted because it was either not found or the crawler was denied access to it.)"
The Default Content Access Account has full read permissions on the Web application the list resides in. Also it has the required permissions that were the pre-requisites. The main thing is the errors are not consistent as in if a document is shown to be not crawled today tomorrow it is being crawled and also there are no checked out documents.But the number of errors are pretty much consistent i.e about 150-160 crawl errors. I also checked the ULS logs but it didn't show anything. Need some help here.
