It seems odd that there are four gdm processess wait()ing and yet the
three zombies aren't disappearing...  This is really looking like a
kernel bug (or maybe even a hardware issue?) to me.

Are the wait()ing processess (24250, 24415, 23707) the parents of the
zombie processess (24730, 26835, 26999)?  Perhaps you could post the
parent PIDs of the processes too (ps -F)?

Incidentally, check out man rt_sigsuspend ...:
