We have a ASP.NET MVC4 application which uses Entity Framework 4.0. When we deploy on the production server, the CPU rises after some time (~2-5h) until nearly 100%. The memory also rises then until maximum. After a while the application pool will be resetted automatically because of the high memory.Server: Windows 2008 R2 Standard SP1IIS: 7 (V 7.5.7600.16385)Only one application pool and one webapplication is running.Stacktrace from Debug Diagnostic Tool of the thread which consumes most of the CPU:\[code\]SNIReadSyncOverAsync(SNI_ConnWrapper*, SNI_Packet**, Int32) .SNIReadSyncOverAsync(SNI_ConnWrapper*, SNI_Packet**, Int32) System.Web.Hosting.UnsafeIISMethods.MgdIndicateCompletion(IntPtr, System.Web.RequestNotificationStatus ByRef) System.Web.Hosting.UnsafeIISMethods.MgdIndicateCompletion(IntPtr, System.Web.RequestNotificationStatus ByRef) ntdll!NtWaitForSingleObject KERNELBASE!WaitForSingleObjectEx System_Data!SNIReadSyncOverAsync System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_ni!load_config_used System_Data_Entity_ni System_Data_Entity_ni System_Data_Entity_ni System_Data_Entity_ni System_Core_ni System_Core_ni 0x000007fe`99223112 0x000007fe`99222a88 0x000007fe`99222899 0x000007fe`992205cb 0x000007fe`99355596 System_Web_Mvc_ni+138058 System_Web_Mvc_ni+13ca67 System_Web_Mvc_ni+13e71c System_Web_Mvc_ni+13ca03 System_Web_Mvc_ni+13d175 System_Web_Mvc_ni+13cbe9 System_Web_Mvc_ni+1431df System_Web_Mvc_ni+13dade System_Web_Mvc_ni+14f5fe System_Web_Mvc_ni+13b0ef System_Web_Mvc_ni+14f514 System_Web_ni System_Web_ni System_Web_ni System_Web_ni System_Web_ni System_Web_ni System_Web_ni System_Web_ni clr!UMThunkStub webengine4!W3_MGD_HANDLER:
