OK, I suggest that you set up a proper handshake. Currently your scenario is like this:
server -- write size
client -- read size
server -- write data_buffer
client -- read data_buffer
Change that to:
server -- write size
client -- read size
client -- write ACK
server -- read ACK
server -- write data_buffer
client -- read data_buffer
client -- write ACK
and so on....
So it will never be that your server is continuously writing to a socket that the client is not able to read cause it crashed...

write(STDOUT_FILENO,&mpid,sizeof(pid_t));

buffer
buffer(3) Library Functions Manual buffer(3)
NAME
buffer.h - generic read/write buffering
SYNTAX
#include <buffer.h>
buffer* buffer_0; /* like stdio's stdin */
buffer* buffer_1; /* like stdio's stdout */
buffer* buffer_2; /* like stdio's stderr */
DESCRIPTION
buffer.h provides a generic buffer interface that can be used for read and write buffering. Buffers must be initialized with buffer_init.
A buffer can only be used for reading or writing at the same time, not both.
Unlike stdio, these write buffers are not flushed automatically at program termination; you must manually call buffer_flush, buf-
fer_putsflush, buffer_putflush or buffer_putnlflush.
EXAMPLE
See buffer_init(3) for example read buffer code. Here is typical code for printing an error message on stderr:
#include <buffer.h>
buffer_puts(buffer_2,"error: got only ");
buffer_putulong(buffer_2,got);
buffer_puts(buffer_2," bytes, but expected at least ");
buffer_putulong(buffer_2,expected);
buffer_putsflush(buffer_2," bytes!");
