OSX: Stuck or Zombie processes

So, can any OSXers out there tell me what to do about this? top reports stuck processes, and they show up as Z in ‘ps’. I can’t kill them, or kill -9 them. How can I make them go away?

rbowen@wooga26 ~ % ps aux | grep Z  
USER       PID %CPU %MEM      VSZ    RSS   TT  STAT STARTED      TIME COMMAND
root       195   0.0  0.0        0      0   ??  Z     4:40PM   0:00.00 (netstat)
rbowen     194   0.0  0.0        0      0   ??  Z     4:40PM   0:00.00 (perl)

Also, I’d kinda like to know why these processes are starting on a reboot, and getting stuck immediately after boot.

Still investigating …
