Consider the following scenario:
In this scenario, you notice that only two expired user-state stores are deleted. Additionally, the Smpmgr.log file indicates that the first user-state store deletion was successful but that the second deletion failed, and you receive the following error message:
CheckAndDeleteSMPStores failed with error code (80004005)
