Help understanding error in LocalClient.ProcessInternalMessages

Unity Engine

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 -

private void ProcessInternalMessages()
{
    if (m_InternalMsgs.Count == 0)
    {
        return;
    }

    // new msgs will get put in m_InternalMsgs2
    List<InternalMsg> tmp = m_InternalMsgs;
    m_InternalMsgs = m_InternalMsgs2;

    // iterate through existing set
    foreach (var msg in tmp)
    {
        if (s_InternalMessage.reader == null)
        {
            s_InternalMessage.reader = new NetworkReader(msg.buffer);
        }
        else
        {
            s_InternalMessage.reader.Replace(msg.buffer);
        }
        s_InternalMessage.reader.ReadInt16(); //size
        s_InternalMessage.channelId = msg.channelId;
        s_InternalMessage.conn = connection;
        s_InternalMessage.msgType = s_InternalMessage.reader.ReadInt16();

        m_Connection.InvokeHandler(s_InternalMessage);
        m_FreeMessages.Push(msg);
        connection.lastMessageTime = Time.time;
    }

    // put m_InternalMsgs back and clear it
    m_InternalMsgs = tmp;
    m_InternalMsgs.Clear();

    // add any newly generated msgs in m_InternalMsgs2 and clear it
    foreach (var msg in m_InternalMsgs2)
    {
        m_InternalMsgs.Add(msg);
    }
    m_InternalMsgs2.Clear();
}

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.
