FIX: Statistics may not display correctly for some COM+ applications on a computer that is running Windows Server 2003

Statistics may not display correctly for some Microsoft COM+ applications on a computer that is running Microsoft Windows Server 2003. If you experience this issue, you may see the following symptoms:

• The process id and the component statistics are not displayed in Component Services for some COM+ applications that are running on the affected computer.
• If the statistics are not displayed for a COM+ application that Microsoft Application Center Component Load Balancing (CLB) uses, all activation requests are routed to the affected computer.
• The COM+ System Application service may unexpectedly quit (crash) on the affected computer. When this symptom occurs, an event may be logged in the Application log. This event will have a call stack that is similar to the following:

  comsvcs!CLinkable::InsertBefore+0x12
  comsvcs!Map<_GUID,CDataPerCLSID *,HashGUID,CFailFastingAllocator>::newAssoc+0x4f
  comsvcs!Map<_GUID,CDataPerCLSID *,HashGUID,CFailFastingAllocator>::add+0x52
  comsvcs!CTrackerServerImpl::PushAppData+0x366
  comsvcs!CTrackerServer::PushAppData+0x29

This problem occurs because race conditions corrupt the hash table that is used for COM+ statistics.
