SYMPTOMS

Consider the following scenario:
  • An event consumer uses Windows Management Instrumentation (WMI). WMI provides asynchronous delivery of events.
  • The event consumer registers an IWbemObjectSink interface with WMI. The event consumer does this to receive DCOM callbacks that contain these events.
  • The event consumer uses the same IWbemObjectSink interface for many such event registrations.
In this scenario, the consumer's DCOM connection may be lost because of network issues or because the consumer stops responding (hangs). If the consumer's DCOM connection is lost, each event registration remains active inside WMI. Therefore, WMI consumes resources for each registration that is associated to the IWbemObjectSink interface. WMI consumes these resources until a failed delivery attempt occurs for each registration.

CAUSE

This problem occurs if an event consumer loses connectivity with WMI. This problem also occurs if a WMI client loses DCOM communication with WMI because of network problems.
