I receive error 'The catalog is corrupt' when performing an Index Server search, what can I do?

A. Index Server catalogs can be caused by unsafe computer shutdowns, system crashes, or applications that write to or lock the catalog files while Index Server is active.

Normally, Index Server attempts to fix any corruption automatically; however, sometimes it is necessary to manually fix the corruption.

To do manually fix the corruption, stop and restart the Content Index service, For Index 1.x, stop and restart the World Wide Web service, under Windows 2000 start the Computer Management MMC snap-in, expand 'Server Applications and Services', right click on 'Indexing Service' and stop then start.  This normally causes Index Server to rebuild the catalog.

If this does not work, stop Index Server again, locate the Catalog.wci folder, and delete the contents of the folder. This manually deletes the catalog. When you restart Index Server, the catalog is re-created.

This can also occur when a file is unfilterable and the Filter Retries is set to a number greater than 4. When this happens, the information that the filter process sends to the Content Index Service (CISVS) causes the CISVS to report that the in-memory catalog information is corrupt, even though the data on the drive is fine.

To correct set retry value to 4 or less:

  1. Start the registry editor (regedit.exe)
  2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex
  3. Double click FilterRetries
  4. Change to 4 or below and click OK
  5. Restart Index Server
