I have been getting the error in my event log #1827 because my database is exceeding the 4096MB size limit for the free version of SharePoint 2010 Foundatins. I have found in the DB the MSSCrawlURL & it's size is enormous. It is almost 3GB. Can I safely delete the data in this table without causing any issues with the SharePoint? I've also discovered several other DBO's that have rather alrge size such as MSSDeleteList, MSSCrawlDeletedURL, MSSCrawlURLLog, etc....Can I delete any of the data in these tables to regain some space?
