EVT_WDSMCS_E_CP_MEMORY_LEAK

EVT_WDSMCS_E_CP_MEMORY_LEAK is a Windows Deployment Services (WDS) Multicast Server result. It indicates that the provider completed shutdown but did not release one or more allocations tracked by WDS Multicast Server.

What to check

  • Review provider ownership rules for every allocation created during initialization, instance, and content operations.
  • Use leak detection in a staging environment to identify the allocation path before restarting services repeatedly.
  • Treat the provider as unreliable for long-running deployments until the cleanup defect is corrected.
