SYMPTOMS
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.

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



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



MORE INFORMATION
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.
