Symptoms

When you perform the Volume Shadow Copy Service (VSS) backup of Exchange databases in a Microsoft Exchange Server 2010 environment, the memory usage of the MSExchangeRepl.exe process keeps increasing. When this issue occurs, the backup operation may fail. Additionally, the following events are logged in the Application log on the Exchange Server 2010 server:
