SYMPTOMS
You may encounter a memory leak in the Remote Procedure Call Server Service (RPCSS, or Svchost.exe).



CAUSE
RPCSS makes synchronous calls to track object identifiers (OIDs) for clients as part of the Distributed Component Object Model (DCOM) pinging mechanism. During this process, RPCSS acquires a handle and memory, which are not released if these clients are not pumping window messages efficiently. This causes a handle and memory resource leak in the Svchost.exe process.
