Dot net Application is hanging while accessing crystal report DLL (Crpe32.Dll)
Hi,
In one of our client we are having one web application uses Crystal Reports 10.2 in Visual Studio 2005. In this application in last one month we are getting hang issue in morning (Business start times while access crystal report). To solve this we are doing app pool restarting.Sometime single app pool restareting is not solving the problem we are doing 2 to 3 times.(We sheduled app pool recycle everyday night 12 O clock)
Based on this issue we analysed the windows crash dump using windebug tool and we found Lock problem in Crpe32.dll. I have mentioned those windebug results below. Please review and provide some permant fix for this problem. If you are required anymore details please let me know.
Thanks in advance.
