I can preview a report I've written in VS (BIDS) without error. However, when I've deployed it to the report server, I'm unable to execute the report.  I receive the following error:


Reporting Services Error

  • Execution 'ucv5xtu2x2uvhfjmjkfmfy45' cannot be found (rsExecutionNotFound)

SQL Server Reporting Services


The report contains a chart that RS is rendering. Does something need to be turned on or is the error unrelated to charting?  In any event, I'm stumped.  Any ideas would be greatly appreciated!

SharePoint 2010 Reporting Services report on sharepoint list rsExecutionNotFound

I cannot get SQL Reporting Services 2008 R2 to work with a datasource that is a sharepoint list.  Reporting services seems to work fine setup in SharePoint 2010 Integrated mode. When I try and run a report that is based on a sharepoint list, I immediatly get the following error: The report execution tp15sp4515l3seqqo4do3e45 has expired or cannot be found. (rsExecutionNotFound) This seems to be something I am doing wrong with the sharepoint configuration, I would guess.  I haven't tried a regular database query, but they used to work when reporting services was configured for native mode.  So I assume this is just a problem connecting to sharepoint 2010 lists, with the new SharePoint 2010 List connection type. Edit This has got to have something to do with a permission setting for the app pool account of sharepoint.  I read something once where it said you had to grant it permissions, but every guide I've found since then doesn't mention anything about it. This log entry is where the problem seems to be occuring, I just don't know what permissions to give TESTDOMAIN\spweb which is the app pool account. library!ReportServer_0-3!1bdc!09/01/2010-09:58:03:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ReportServerStorageException: , An error occurred within the report server database.  This may be due to a connection failure, tim

Issue - The report execution has expired or cannot be found. (rsExecutionNotFound)


Hello Experts,

I am running a huge SSRS 2008 report (that returns 2 million records) and it gets rendered sometimes and sometimes it gives me an error,

"The report execution <some string> has expired or cannot be found. (rsExecutionNotFound)”.

When I see SQL Server log after this issue comes I see following message there;

"A significant part of sql server memory has been paged out. This may result in performance degradation. Duration: 300 seconds. Working set(KB): 97672, memory utilization 42%"

IMPORTANT point to note here is when I am running reports with 1 million records or smaller than that, then I am able to execute them successfully without any issue.

I am using SSRS 2008 64 bit, Win Server 2003 64 bit. RAM is 8GB.

Please help me to know what are these issue, are these two issues related and how to fix it?
