An unexpected error occurred in Report Processing. (rsInternalError)

Hi,

1. Are you using the NLB? If possible, please turn off the NLB temporally to see whether the is gone.

2. Try to enlarge the execution timeout value in the web.config.

a. Backup the web.config first. Then, open the web.config from the report server folder, located at c:\Program Files\Microsoft SQL Server\MSRS11.<instance name>\Reporting Services\ReportServer\ by default.

b. Find out the following line in the file.

<httpRuntime executionTimeout="9000" />

c. Modify the attribute value from 9000 to 36000. Save the web.config file and restart the reporting service.

3. Restart the reporting service and then you need reproduce this issue, and collect the new reporting service logs.

Thanks.
