Office 97 Filter OffFilt.dll Causes Index Server to Loop Infinitely When Parsing an Excel Spreadsheet

• Microsoft Index Server version 2.0
• Microsoft Internet Information Server version 4.0
• Microsoft Office 2000

SYMPTOMS

An application thread may stop responding and CPU utilization may approach 100 percent for the Microsoft Index Server running on the Microsoft Internet Information server 4.0 (IIS4), as observed in Task Manager or in Performance Monitor. This problem can occur when the Index Server is attempting to index an Excel spreadsheet (.xls extension) that contains Japanese characters.

CAUSE

When the Index Server parses an Excel spreadsheet, it loads the Offfilt.dll file to parse the spreadsheet. There are times when the buffer used in the Offfilt.dll file is too small for certain Japanese characters, and this causes Index Server to go into an infinite loop.

RESOLUTION

STATUS

Microsoft has confirmed this to be a problem in Microsoft Office 97.
