The EdgeTransport.exe process consumes 100 percent of CPU resources on an Exchange Server 2010 Edge Transport server

Applies to: Exchange Server 2010 StandardExchange Server 2010 Enterprise


The EdgeTransport.exe process may consume 100 percent of CPU resources on a Microsoft Exchange Server 2010 Edge Transport server. When this issue occurs, the Edge Transport server stops responding. 

Note This issue may occur when the Edge Transport server is under a heavy workload, and frequent changes are made to the transport configuration files.


This issue occurs because multiple threads access an object to retrieve certain TransportConfigContainer properties that are out of the schema at the same time on the Edge Transport server.


To resolve this issue, install the following update rollup:
2685289 Description of Update Rollup 3 for Exchange Server 2010 Service Pack 2


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
