I am using Exchange 2010, and recently I deploy SP2 rollup 2 patch to either Hub and mail store servers. I found the error mail related to msexchangerepl shown below:- Log Name: Application Source: ESE Date: 6/3/2012 8:30:31 PM Event ID: 489 Task Category: General Level: Error Keywords: Classic User: N/A Computer: EXCH-M2.kehk.com.hk Description: msexchangerepl (2208) Log Verifier E01 48282742: An attempt to open the file "F:\DB02\inspector\E010007704A.log" for read only access failed with system error 32 (0x00000020): "The process cannot access the file because it is being used by another process.

Hello, The exchange replication service on the source server initiates an ESE streaming backup via the Exchange Information Store service interface. Are there any errors in application log? What are you using for backups? Best Regards, Lisa

I am having the exact same issue. There along with the 489 error i get this in the application log: Log Name: Application Source: MSExchange Common Date: 6/8/2012 11:38:36 AM Event ID: 4999 Task Category: General Level: Error Keywords: Classic User: N/A Computer: XXXXXXXXXXXXXXXXXX Description: Watson report about to be sent for process id: 7832, with parameters: E12, c-RTL-AMD64, 14.02.0298.004, msexchangerepl, System, M.W.UnsafeNativeMethods.EvtClose, System.AccessViolationException, 7a59, 02.00.50727.5456. ErrorReportingEnabled: False I also get this in the System log: Log Name: System Source: Service Control Manager Date: 6/8/2012 11:38:36 AM Event ID: 7031 Task Category: None Level: Error Keywords: Classic User: N/A Computer: XXXXXXXXXXXXXXXXX Description: The Microsoft Exchange Replication service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 5000 milliseconds: Restart the service. These errors are happening constantly, I have verified no backup jobs are running, exclused for AV is set on the DB folders and all the folders have the correct security on them. Everything points to applying SP1 update 4 to resolve, which is hard to do when your running SP2 Update 2. Any ideas or suggestions would be helpful. Thanks, Dewayne Holiway
