Workflow in wait status due to System.NullReferenceException in CRM 2011

  I have a case audit workflow in CRM 2011, and it is triggered whenever there is a change made to the record status.  Sometimes WF succeeds, but most of the time, it's stuck in wait status.  The error message is the following:

  Workflow paused due to error: Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.
     at System.Activities.Statements.InteropExecutor.TranslateExecutionStatus()
     at System.Activities.Statements.InteropEnvironment.Execute(Activity definition, NativeActivityContext context)
     at System.Activities.Statements.Interop.Execute(NativeActivityContext context)
     at System.Activities.NativeActivity.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager)
     at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)
  

  What might be wrong and how may I fix this?

  Thanks in advance.
