ProcessReceive引发NullReferenceException

[att1008]

Framework 版本: v4.0.30319
说明: 由于未经处理的异常，进程终止。
异常信息: System.NullReferenceException
在 SuperSocket.ClientEngine.AsyncTcpSession.ProcessReceive(System.Net.Sockets.SocketAsyncEventArgs)
在 SuperSocket.ClientEngine.AsyncTcpSession.StartReceive()
在 System.Net.Sockets.SocketAsyncEventArgs.OnCompleted(System.Net.Sockets.SocketAsyncEventArgs)
在 System.Threading.ExecutionContext.RunInternal(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
在 System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
在 System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object)
在 System.Net.Sockets.SocketAsyncEventArgs.FinishOperationSuccess(System.Net.Sockets.SocketError, Int32, System.Net.Sockets.SocketFlags)
在 System.Net.Sockets.SocketAsyncEventArgs.CompletionPortCallback(UInt32, UInt32, System.Threading.NativeOverlapped*)
在 System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32, UInt32, System.Threading.NativeOverlapped*)

如果并发大的情况下会不定时出现这个问题

我利用DNSPY工具，在ProcessReceive方法里面抓了下异常，输出发现是 ProcessReceive 方法的参数SocketAsyncEventArgs为null
