your program on p16 seg-faults (bad address, etc - could be your program,
some library, or marginal hardware).  p11 is trying to communicate with it,
and quite sensibly reports that the socket between them has disappeared:
/usr/include/asm/errno.h:#define        ECONNRESET      104     /* Connection reset by peer */
