Consider the following scenario in Microsoft Office SharePoint Portal Server 2003. You use a third-party single-threaded IFilter for files that have certain file name extensions. When you perform an incremental update or a full update of content on the portal site, it takes a longer time for the crawl to be completed. When you view the gatherer log after the update operation is completed, some files in document libraries have a Retry status. That is, you see entries that are similar to the following for some files:
This issue occurs because the Mssdmn.exe process in SharePoint Portal Server 2003 copies a file from the source to the temporary folder on the server two times instead of one time. SharePoint Portal Server 2003 does this if a single-threaded IFilter is required for the file that is being copied.
Note When you see many entries that have a Retry status, the third-party IFilter may be single threaded. While this is not the only reason that you may see a Retry status in the gatherer log, it is the most common reason.
