if you add -d to the command line it will _NOT_ write its internal messages
to the log file only to the console.

Could you please put a breakpoint to afdoor_server_proc, and check its
parameters when log messages arrive?

afdoor_server_proc has the following parameters:

void afdoor_server_proc(void *cookie, char *argp, size_t arg_size,
door_desc_t *dp, size_t n_desc)

* cookie is a parameter can be passed to this callback function, it contains
  the pointer of the afdoor_source pointer
* argp should contain the log message itself
* arg_size is the number of characters in argp
* dp is an array of n_desc elements, which may contain additional arguments 

The log message itself should be pointed by argp. 

void afdoor_server_proc(void *cookie, char *argp, size_t arg_size, door_desc_t *dp, size_t n_desc)
{
        CAST(afdoor_source, handler, cookie);
        if (argp) {
                struct log_info *msg = make_log_info(c_format("%z", argp, arg_size));
                HANDLE_LOG(handler, msg);
        }
        door_return(NULL, 0, NULL, 0);
}

Please add the last line of this function to your afdoor.c (the one with the
door_return invocation)
