what was thta?

from here :

Defunct processes are processes that have become corrupted in such a
way the no long can communicate (not really the right word, like
signal each other) with their parent or child process. So kill the
parent or child and 99% of the time (around here at least) the defunct
process will go away! No parent or child, your out of luck, or look
for a stuck automount.
