Problem description: | |
When unloading an AppDomain in which the IBM.Data.DB2 provider was loaded and used, an ObjectDisposedException is intermittently encountered: Exception Information: System.ObjectDisposedException Stack: at System.Runtime.InteropServices.SafeHandle.DangerousAddRef(Boolea n ByRef) at Microsoft.Win32.Win32Native.SetEvent(Microsoft.Win32.SafeHandles .SafeWaitHandle) at System.Threading.EventWaitHandle.Set() at IBM.Data.DB2.DB2Trace.CloseTraceConsole() at IBM.Data.DB2.DB2ConnPool.FreeDB2ConnPool() at IBM.Data.DB2.DB2ConnPool.Finalize() This error has not been observed as the default AppDomain closes (at process shutdown). Instead, this error has been observed only in programs which host AppDomains that are unloaded. | |
