    I got this error a couple times last night, and I'm not too sure what to say about it -

    Looking over the loops in ProcessInternalMessages, it seems like this error should never happen. So why would it?

    Including the LocalClient.ProcessInternalMessages code -

    Code (CSharp):
    1. private void ProcessInternalMessages()
    2. {
    3.     if (m_InternalMsgs.Count == 0)
    4.     {
    5.         return;
    6.     }
    7.  
    8.     // new msgs will get put in m_InternalMsgs2
    9.     List<InternalMsg> tmp = m_InternalMsgs;
    10.     m_InternalMsgs = m_InternalMsgs2;
    11.  
    12.     // iterate through existing set
    13.     foreach (var msg in tmp)
    14.     {
    15.         if (s_InternalMessage.reader == null)
    16.         {
    17.             s_InternalMessage.reader = new NetworkReader(msg.buffer);
    18.         }
    19.         else
    20.         {
    21.             s_InternalMessage.reader.Replace(msg.buffer);
    22.         }
    23.         s_InternalMessage.reader.ReadInt16(); //size
    24.         s_InternalMessage.channelId = msg.channelId;
    25.         s_InternalMessage.conn = connection;
    26.         s_InternalMessage.msgType = s_InternalMessage.reader.ReadInt16();
    27.  
    28.         m_Connection.InvokeHandler(s_InternalMessage);
    29.         m_FreeMessages.Push(msg);
    30.         connection.lastMessageTime = Time.time;
    31.     }
    32.  
    33.     // put m_InternalMsgs back and clear it
    34.     m_InternalMsgs = tmp;
    35.     m_InternalMsgs.Clear();
    36.  
    37.     // add any newly generated msgs in m_InternalMsgs2 and clear it
    38.     foreach (var msg in m_InternalMsgs2)
    39.     {
    40.         m_InternalMsgs.Add(msg);
    41.     }
    42.     m_InternalMsgs2.Clear();
    43. }
    I'd guess one of those foreach loops is messing up..probably the first one. Looking at this a bit deeper, it seems like this function is only really called by UNetStaticUpdate so I'm not totally sure how this could be breaking.
