Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt

Hi,

I am intermittently getting the following error while running the recording bot.
Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at Microsoft.Skype.Bots.Media.AudioFramePlayer.CopyMemory(IntPtr dest, IntPtr src, UInt32 count) at Microsoft.Skype.Bots.Media.AudioFramePlayer.<CopyAndSendData>d__46.MoveNext() at System.Runtime.CompilerServices.AsyncTaskMethodBuilder.Start[TStateMachine](TStateMachine& stateMachine) at Microsoft.Skype.Bots.Media.AudioFramePlayer.CopyAndSendData(AudioMediaBuffer sourceBuffer, MediaBuffer destinationBuffer) at Microsoft.Skype.Bots.Media.AudioFramePlayer.<DequeueAndProcessAsync>d__47.MoveNext() at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Runtime.CompilerServices.AsyncMethodBuilderCore.MoveNextRunner.Run() at System.Runtime.CompilerServices.AsyncMethodBuilderCore.<>c__DisplayClass4_0.<OutputAsyncCausalityEvents>b__0() at System.Runtime.CompilerServices.TaskAwaiter.<>c__DisplayClass11_0.<OutputWaitEtwEvents>b__0() at System.Threading.Tasks.AwaitTaskContinuation.RunOrScheduleAction(Action action, Boolean allowInlining, Task& currentTask) at System.Threading.Tasks.Task.FinishContinuations() at System.Threading.Tasks.Task.Finish(Boolean bUserDelegateExecuted) at System.Threading.Tasks.Task.ExecuteWithThreadLocal(Task& currentTaskSlot) at System.Threading.Tasks.Task.ExecuteEntry(Boolean bPreventDoubleExecution) at System.Threading.ThreadPoolWorkQueue.Dispatch()

Can somebody help me with this ?

Start by reproducing the recording bot failure and inspect the stack trace entry points in Microsoft.Skype.Bots.Media.AudioFramePlayer, especially CopyMemory and CopyAndSendData. Done means identifying the cause of the intermittent AccessViolationException and verifying that the recording bot no longer triggers it.
