Crystal Repors 2008 upgrade - IIS worker process hanging

41 Views

We're running a .NET webapp that's using CR embeded reports. We just upgraded from CR 10 to CR 2008 (SP2 - 12.2.0.290). The upgrade seemed to go fine, but once we had multiple users on the system, reports began to stop responding, and eventually IIS would crash. It looks like uf12manager.dll is faulting and bringing down w3wp.exe. Now we're having to recycle the worker process just to keep the site running. Memory doesn't seem to be an issue - we never come close to using the available amount. The application worked fine before the upgrade to CR 2008, and no other changes were made. The application is a VB .NET Webapp running on Framework 1.1. I'd really hate to roll back the CR upgrade, but at this point I'm not sure what else to do.
