We currently have a SharePoint 2010 Single server farm. The patch level is SP1 with June CU. The issue is with incremental or full crawls of content sources. The error is as follows:
The system cannot find the path specified. (Exception from HRESULT: 0x80070003)
The paths that are used http://intranet and http://mysites. If I were to reset the index and do a full crawl we would have success with no error as stated above. The problem is always on subsequent crawls.
We also confirmed the permissions of the gthrsvc_Osearch14 is set appropriately for the search acct.
