I have a SQL Server Reporting Services 2005 installation that has worked great for a few years now, but has been giving me occasional glitches recently.
I'm using the default reporting services website instead of embedding reports into my application, which has proven a very efficient way to deploy the reports. The OS is Windows Server 2003 and the reports are being viewed on IE8 running XP.
It's not a big deal. Refreshing the browser brings the report right up each time. I guess it might be a cacheing issue. It does scare users, so it would be nice to squash this bug.
Any ideas?

Try this (extending the "report session" timeout) http://blogs.msdn.com/b/jgalla/archive/2006/10/11/session-timeout-during-execution.aspx
Here is a thread that might help...not sure if you tried it already.
In this case updating Microsoft.ReportViewer.WebForms.dll was a fix.
I also saw where it could be caused by a problem with NT Authority\Network Service account.
A quick "Google" with SSRS 2005 Execution "cannot be found" produced quite a few other options as well.
HTH
Take a look here :
http://blogs.msdn.com/jgalla/archive/2006/10/11/session-timeout-during-execution.aspx
This can happen when a report takes a long time to run, using a script with rs.exe to increase the RS session lifetime may well help.
I have answered this question in this thread.
It is to do with the execution context in the Session expiring.
In my case, this error ocurred only in the Browsers Internet Explorer 8 and Internet Explorer 9 with reports that takes more than 20 minutes for execute. I solved this problem optimizing the sql query procedure ( before optimize took 30 minutes to execute ) and now takes 3 minutes.
I tried to configure increasing the session timeout in ReportManager configuration but anything solve the problem.
This error is weird because in Google Chrome and Firefox works fine!
the reason of this issue may be below:
1 - > your login has expired OR
2 - > The server on which SSRS report deployed, below services has stopped
a - > MS SQL SERVER
b - > SQL Server Agent is not running
to resolve go to the server and start these services
None of the aforementioned things worked for me. My reports aren't working from the Report browser interface, even though it used to. It does however work from the server URL.
eg) The /ReportServer context works fine, and NOT the /Reports context whilst browsing to reports.
This is ok since I can still upload reports, and our applications use the server URL.
