We have a C# Web Application that uses Crystal Reports basic runtime for visual studio 2008 64bit. In production, our application is intermittently hanging. The crash dump analysis indicates that a Crystal Reports assembly is causing blocked threads (i.e. deadlock). The results of crash dump 1.png 2.png 3.png 4.pnganalysis and diagnostic information about one of the affected machines is attached. When this error occurs, the users are simply trying to view the report. The database is SQL Server 2016 standard but, the report does genrate properly. To add more information we have added our server to domain and applied group policies and not sure any security cause this. When the application hangs W3WP strucks at 50% of cpu usage and never gets down until we kill the process. Can someone please provide advice and/or feedback on how to interpret and/or further analyze the information in the dump analysis for troubleshooting purposes.
