DPR-ERR-2056 The Report Server is not responding.Error

[redmist]

I get the following error when i run some heavy reports where the output is to be generated in Excel. The report runs for some time before failing.

DPR-ERR-2056 The Report Server is not responding. Handler trace back: [the_dispatcher] com.cognos.pogo.handlers.performance.PerformanceIndicationHandler [the_dispatcher] com.cognos.pogo.handlers.logic.ChainHandler [service_lookup] com.cognos.pogo.handlers.engine.ServiceLookupHandler [load_balancer] com.cognos.pogo.handlers.logic.ChainHandler [lb_forwarder] .


I tired to investigate further using logviewv2.exe and i noticed the following
BI BusTKServer  Idle too long - Suicide stop

Is this due to the fact that the BI process was waiting for the data to be retrieved and went over the time limit or is this message normal

Does anyone have any ideas about this issue. I have seen few posts related to this error but they seem to be about dragging columns over to the report.

Thanks

I seem to have found a solution for my specific situation

I had modified the rsvpproperties.xml file to increase the performance by keeping all the data in memory instead of writing to file.

<property>VirtualMemoryDiagnostics</property>
                    <value type="long">2</value>
This value of 2 will do the following:
Turns off paging to disk, all objects will be held in memoryTurns off paging to disk, all objects will be held in memory

Due to this when i ran a large report, CCLVPage.... files were not getting generated in the Temp folder.

After i reverted back to the default setting, CCLVPage....files started getting created and the report ran successfully. The 2 CCLVPage files that were created were 700 MB and 850 MB.

These files probably put the process over 2 GB memory. This in turn was probably killing the BiBus process

I read about modifying the rsvpproperties.xml file in best practice document which i'm not able to locate now. I will try to find it and post it here.

Hello Folks- We too have applied the patch from Cognos for this issue, no resolution.  We don't have the virtual memory config mentioned previously. We have had a ticket open with support since Nov 2009.  We recently sent our second dmp file to Cognos for analysis, I'll let you know what they say.  As a side note, post supposed fix load, we are seeing some of our scheduled Excel reports generate with blank pages.  Rerun the report and it works.
