CAUSE
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.
RESOLUTION
Add the WSSSingleThreadedFilterExtensions registry entry
To enable this hotfix after you install it, first add the
WSSSingleThreadedFilterExtensions registry entry to the following registry
subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\SPSSearch\Gathering Manager
Then, specify the file name extensions that you want to associate with the
single-threaded IFilter. The single-threaded IFilter is used for files in
Windows SharePoint Services document libraries that have file name extensions
that you specify.
Warning If you use Registry Editor incorrectly, you may cause serious problems
that may require you to reinstall your operating system. Microsoft cannot
guarantee that you can solve problems that result from using Registry Editor
incorrectly. Use Registry Editor at your own risk.
To enable this hotfix, follow these steps:
1. Add the WSSSingleThreadedFilterExtensions registry entry to
the following registry subkey, and then specify the file name extensions that
you want:
HKEY_LOCAL_MACHINE\Software\Microsoft\SPSSearch\Gathering Manager
To do this, follow these steps:
a. Click Start, click Run, type regedit in the Open box, and
then click OK.
b. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\SPSSearch\Gathering Manager
c. On the Edit menu, point to New, and then click String
Value.
d. Type WSSSingleThreadedFilterExtensions, and then press
ENTER.
e. Right-click WSSSingleThreadedFilterExtensions, and then
click Modify.
f. In the Value data box, type the file name extensions that
you want. The following are two things to consider when you type file name
extensions:
• Do not use a period character (.) before each file name extension that you
type.
• Separate each file name extension with a semicolon character (;).
For example, if you want to use the single-threaded filter for .jpg files, for
.pdf files, and for .gif files, type the following line in the Value data box:
jpg;pdf;gif
g. Click OK, and then click Exit on the File menu to quit
Registry Editor.
2. Restart the Microsoft SharePointPS Search service. To do
this, follow these steps:
a. Click Start, click Run, type cmd, and then click OK.
b. Stop the Microsoft SharePointPS Search service. To do this,
type net stop sharepointpssearch at the command prompt, and then press ENTER.
c. Start the Microsoft SharePointPS Search service. To do
this, type net start sharepointpssearch at the command prompt, and then press
ENTER.
