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:
Log Name: ApplicationSource: MSExchangeReplDate: DateEvent ID: 4122Task Category: ServiceLevel: ErrorKeywords: ClassicUser: N/AComputer: ComputerDescription:The Microsoft Exchange Replication service is terminating. Error The Microsoft Exchange Replication service is using too much memory (XXXX MiB). This exceeds the maximum expected value of XXXX MiB. Default can be overridden by setting registry key SOFTWARE\Microsoft\ExchangeServer\v14\Replay\Parameters\MaximumProcessPrivateMemoryMB.

Error The Microsoft Exchange Replication service has more than XXXX handles, which exceeds the maximum expected value of XXXX. Default can be overridden by setting registry key SOFTWARE\Microsoft\ExchangeServer\v14\Replay\Parameters\MaximumProcessHandleCount.
Cause
This issue occurs because the Exchange replication service VSS writer does not release the references to the XML description of backup components. Therefore, a handle leak occurs.
