NNTP "Disk Space" Expiration Policies May Cause a Memory Leak in Inetinfo.exe

  • Microsoft Commercial Internet System 2.0

This article was previously published under Q249853


When you use Microsoft Commercial Internet System (MCIS) News version 2.0, you may set expiration policies on an NNTP newsgroup based on:

  • Article age limit ("Article Older than" option in the Expiration property sheet)
  • Total newsgroup directory size limit ("Combined group Size" option)
  • Article age and newsgroup size limits ("Both" option)

When you define NNTP "Combined group Size" or "Both" expiration policies, the memory usage of the "Internet Information Services" process (Inetinfo.exe) grows every time the expiration runs.


A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Commercial Internet System service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:

   Date       Time     Size      Version      File name     Platform
   11/29/1999 21:16    761,104   5.5.1877.38  nntpsvc.dll   x86 
   11/30/1999  1:12  1,151,248   5.5.1877.38  nntpsvc.dll   Alpha


Microsoft has confirmed that this is a problem in Commercial Internet System 2.0 and 2.5.


At periodic interval defined by the NewsCrawlerTime NNTP registry parameter(default value is 30 minutes), NNTP Service wakes up and applies the expiration policies. If an expiration policy contains 10 newsgroups, each with a name length of 100 bytes, the size of the memory leak will approximately be 10000 bytes every "NewsCrawlerTime" minutes.
