it think this bug might actually be a bug in the jk layer...

in ajp_process_callback, here is the block of code that handles sending the
next chunk of data from the webserver to tomcat:

--- snip ---
        case JK_AJP13_GET_BODY_CHUNK:
            {
                unsigned len = (unsigned)jk_b_get_int(msg);
                jk_log(l, JK_LOG_DEBUG, "received JK_AJP13_GET_BODY_CHUNK,
len=%d\n", len);

                if(len > AJP13_MAX_SEND_BODY_SZ) {
                    len = AJP13_MAX_SEND_BODY_SZ;
                }
                if(len > ae->left_bytes_to_send) {
                    jk_log(l, JK_LOG_DEBUG, "len > ae->left_bytes_to_send
(%d > %d)\n",
                           len, ae->left_bytes_to_send);
                    len = ae->left_bytes_to_send;
                }
                if(len < 0) {
                    len = 0;
                }

                /* the right place to add file storage for upload */
                if ((len = ajp_read_into_msg_buff(ae, r, msg, len, l)) >= 0)
{
                    r->content_read += len;
                    return JK_AJP13_HAS_RESPONSE;
                }                  

                jk_log(l, JK_LOG_ERROR, "Error ajp_process_callback -
ajp_read_into_msg_buff failed\n");
                return JK_INTERNAL_ERROR;           
            }
            break;
--- end snip ---

in this line:

  if ((len = ajp_read_into_msg_buff(ae, r, msg, len, l)) >= 0){

shouldn't pmsg (the post message) be read into, not msg?  i don't know the code 
well enough to be sure....

anyway, i was running into a problem with an infinite loop in the ajp layer.
when i made this change, the problem went away.
