We are running a report that has benn failing at exactly 10 minutes with the following log entry: ERROR: Reporting Services error Microsoft.ReportingServices.Diagnostics.Utilities.ReportServerHttpRuntimeClientDisconnectionException: A client has disconnected from the Report Server Web service application domain ReportServer_MSSQLSERVER_0-4-128662266757054021. No corrective action is required. An error code has been submitted to ASP.NET to release the connection. The error code is 800708CA. ---> System.Runtime.InteropServices.COMException: This network connection does not exist. (Exception from HRESULT: 0x800708CA) It seems to be a timeout, but I can't determine where this might be happening. Current settings that I believe might be relevant are set as follows: Timeout Seconds Minutes Report Execution Timout 1800 30 Session Timout 6000 100 External Images Timeout 600 10 System Report Timeout 1800 30 Cleanup Cycle Minutes 1200 20 SQL Command Timeout 60 1 DatabaseQueryTimeout 120 2 Running Request Scavenger Cycle 60 1 Running Request DB Cycle 60 1 Running Requests Age 30 0.5 Max Schedule Wait 5 0.083333 Process Timeout 150 2.5 Process Timeout Gc Extension 30 0.5 Service Recycle Time 720 12 http runtime execution timeout 9000 150 Any help would be appreciated.

We get similar errors in our log files. IE seems to hang we try to do a Print Preview or an Excel/PDF export.
