[Wed Jun 15 16:37:08.004 2011] [27849:1123723584] [error] ajp_connection_tcp_get_message::jk_ajp_common.c (1312): (local) can't receive the response body message from tomcat, tomcat (127.0.0.1:8009) has forced a connection close for socket 14

Comment 1 wangxinsheng CLA 2011-06-16 02:48:14 EDT 
While debuging ,I found that  the class of Ajp13Generator has a method which can't executed for the _buffer is not null. the source code as follows:
 private void initContent() throws IOException
    {
        if (_buffer == null)
        {
            _buffer = _buffers.getBuffer(_contentBufferSize);
            _buffer.setPutIndex(7);
            _buffer.setGetIndex(7);
        }
    }

Next step ,the method increaseContentBufferSize in class AbstractGenerator as follows has inited the buffer field.  
 public void increaseContentBufferSize(int contentBufferSize)
    {
        if (_buffer==null)
            _buffer=_buffers.getBuffer();
        if (contentBufferSize > _buffer.capacity())
        {
            Buffer nb = _buffers.getBuffer(contentBufferSize);
            nb.put(_buffer);
            _buffers.returnBuffer(_buffer);
            _buffer = nb;
        }
    }

 the buffer of 6.x has not inited,as follow is jetty6.1.22 source code :
public void increaseContentBufferSize(int contentBufferSize)
    {
        if (contentBufferSize > _contentBufferSize)
        {
            _contentBufferSize = contentBufferSize;
            if (_buffer != null)
            {
                Buffer nb = _buffers.getBuffer(_contentBufferSize);
                nb.put(_buffer);
                _buffers.returnBuffer(_buffer);
                _buffer = nb;
            }
        }
    }
