MeetingPlace Gateway SIM

4.2.1.11 - 4.2.1.15

Problem Description

Note: This Field Notice is a legacy Latitude Field Notice that has been converted to the Cisco format so the information would remain available to their customers.

A memory leak was introduced in the mpgwcm.dll that controls gateway event logging in the most recent versions of GWSIM, 4.2.1.11 through 4.2.1.15.

Your system is affected if:

  • You have explicitly upgraded GWSIM to version 4.2.1.11 - 4.2.1.15 on any gateway server.

  • You indirectly upgraded GWSIM to version 4.2.1.11 - 4.2.1.15 by installing a gateway product that contains the faulty version, Outlook 4.2.7.61 or Web 4.3.0.63.

If you have any doubt, verify the version of GWSIM that is running on your gateway server and if necessary obtain the hotfix from CSRC.

Problem Symptoms

Gateways can hang after a while or exhibit other unpredictable errors. In Web, it cannot connect to database, blank page and so on. In Outlook, mpoutlook service cannot start.

Workaround/Solution

Restarting the Web server will temporarily fix the problem.

This hotfix 4.2.1.16 (mpgwcm.dll) can only be installed on top of GWSIM versions 4.2.1.11 to 4.2.1.15

To install this hotfix:

  1. Shutdown all MeetingPlace gateways and eventlog applications.

  2. Shutdown IIS Admin.

  3. Replace \system32\mpgwcm.dll with the patched DLL.

  4. Restart system.

Note:?Gwsim version 4.2.1.16 will not be reflected in Gwstatus, but you can right-click | properties the file to check its version.
