Assume that you use a Microsoft System Center Data Protection Manager (DPM) 2010 server to protect Exchange Server 2010 servers. However, the DPM protection agent service on the protected Exchange Server 2010 servers may stop responding. Additionally, the DPM 2010 server cannot communicate with the Exchange Server 2010 servers. Therefore, the DPM protection agent does not finish performing a backup of the Exchange Server 2010 servers.
This issue occurs because of a deadlock between two threads that are waiting for the same Exchange diagnostic file. This deadlock situation occurs when the DPM 2010 server performs backup operations on the Exchange Server 2010 servers.
To resolve this issue, install the following update rollup:
2661854 Description of Update Rollup 2 for Exchange Server 2010 Service Pack 2
To work around this issue, restart the E14CmdletsWrapper.exe process on the Exchange Server 2010 server.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
