Hi All,

we are facing below error for one of the report

DPR-ERR-2077 Failed to forward the request because the associated external process with PID 10268 is unavailable, either because the process is shutting down, or this was an absolute affinity request and the requested process does not exist anymore. For more information, enable the dispatcher and the external process detailed logs, and reproduce the conditions that caused the error. 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] com.cognos.p2plb.clerver.LoadBalanceHandler [batchreportservicechain] com.cognos.pogo.handlers.logic.ChainHandler [warptask_with_authenticate] com.cognos.pogo.handlers.logic.ChainHandler [do_batch_warp] com.cognos.pogo.handlers.logic.ChainHandler [warptaskmtaChain] com.cognos.pogo.handlers.logic.ChainHandler [warptaskmta] com.cognos.pogo.reportservice.BatchReportServerHand

Unless I'm missing something, that looks like the same error message - just with a different process ID? Can you detail the exact steps you took?

Hi MF,

I opened the report and opened the Query explorer.

we have 4 report pages and  4 report queries .

for each query i made the processing to limited local and saved the report and ran the report.

Thanks,

At this point you need to do some basic troubleshooting to try and isolate the problem. Try scaling it back to just one query and one page at a time to find out if all are problematic or just one. Try evaluating the generated SQL. Try removing portions of a single problematic query to see if you can find where the problem is.

I don't think you've provided anyone with enough information to help you further so best to investigate further and then report back with additional detail.
