Symptoms: Microsoft SharePoint Server 2010 experiences the following symptoms when it crawls content:

 The crawl does not progress and seems to stall.

 The crawl logs show no new crawled documents.

 This event appears in the event log: Event ID: 23 Description: The crawl has been delayed because a disk is full.

Cause: The disk on which the search crawler creates temporary files is running out of space.

Resolution: Free up disk space

 Free up space on the disk on which the crawler creates an index as it searches content.

To free up disk space:

1. Use Disk Cleanup to delete temporary files on the drive where the index files are stored. Use the procedure following this one to determine the location of the index files.

Note:

If the temporary files are located on a drive other than the operating system drive (drive C), you must restart the Microsoft Search Server 2010 service (OSearch) to test the performance of the crawler after you delete the temporary files.
