Hi Vijay,
According to your description, when calling reports in ASPX page, sometimes it throws “DeviceInfo Name already exists Parmeter Name:deviceInfoName” error message.
I would like to know which version of SQL Server you are using. In SQL Server 2008 and later versions, SSRS doesn't use IIS anymore, although it does use the same driver (http.sys) as IIS to manage connections.
In Reporting Service, it control Recycling by setting RecycleTime . The default value is 12 hours. Garbage collection runs continuously as well as when application call the GC function. When the application use garbage collection, Reporting Service is blocked
and waiting for garbage collection to be completed. During this time, Process Monitor misunderstands that Reporting Service is stopped, so Process Monitor stops Reporting Service really and create a dump file.
In configuration settings, ProcessTimeoutGcExtension can affect Reporting Service when garbage collection is in progress. So in your scenario, I would recommend you to modify the RSReportServer.config file to add the ProcessTimeoutGcExtension key. Configuration
settings for Reporting Service are stored in the Reporting Services configuration file(this file locates at xx:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer\rsreportserver.config). For detail information about how
to add the ProcessTimeoutGcExtension key in Reporting Services configuration file, please refer to this article: 
When you use SQL Server 2008 Reporting Services, the ReportingServicesService.exe process may stop responding during CLR garbage collection.
If you have any question, please feel free to ask.
