IIS Crash because of a Application Popup w3wp.exe

Question

We have a report system that runs on a Win2003 Server with Crystal Reports for .NET Framewokr 4.0. We installed the Crystal Runtime 13.0.
Now, every 5 hours the IIS server crash. At the time of the crash we have the following Event in the Event Viewer:
Event Type: Information
Event Source: Application Popup
Event Category: None
Event ID: 26
Description:
Application popup: w3wp.exe - Unable To Locate component: This application has failed to start because SmAgentAPI.dll was not found. Reinstalling the application may fix this Problem.
After a restart of the IIS Service, everthing works fine for another about 5 hours.
Does anyone have a clue for me?

Hello,
What is happening is IIS is running out of memory and the error is popping up in one of our dll's. I don't believe it is the actual cause, CR just can't load any more dll's and that's the one when the system resources run out.
Make sure you are closing and disposing of you report objects when they are done with and using/adding GC.Collect to tell Windows to free up it's freed memory also helps.
To get more info you may need to add logging to your app as well as adding try/catch around every functions and write the catch to a log file to get more info and to help follow the flow.
Thank you
