Yes. I know that zombies/defunct processes don't take up much resources, but parents should NOT exit without terminating their children and cleaning up the environment.

NOTE: - This seems to happen after burning DVD's, even though the burning process is successful with the appropriate finished messages.

As I have been unable to kill or remove this dead processes I reboot daily.  They occur on a regular basis.  ie..

uptime
 23:18:37 up  3:25,  0 users,  load average: 2.96, 2.84, 2.45

Yes, only 3 minutes and 25  seconds yet:-

Tasks: 254 total,   3 running, 234 sleeping,   0 stopped,  17 zombie
Cpu(s):  0.7%us,  4.3%sy,  0.0%ni, 40.3%id, 53.6%wa,  0.7%hi,  0.5%si,  0.0%st
Mem:    904604k total,   895200k used,     9404k free,   101756k buffers
Swap:  1953588k total,    34148k used,  1919440k free,   265384k cached


Yep, 17 zombies in only 3 minutes and 25 seconds.
