These fields are present in queue.dat and usually only contain zeros.

Some fields, like z192, z224 and z7152 are most likely reserved for future use. Whereas other fields are mostly likely padding, or sometimes contain unknown values, e.g. z500 and z528.

grep "unknown stuff" qd.c
/* There is still sometimes unknown stuff in bytes 500-507 and 528 */

grep "z224\[36\]" qd.c
                char    z224[36];

./qd -q queue.dat -d | grep 224
