10.5: Mail, sent messages, and zombie process problems
the ps output shown in this hint gives no indication that these processes are zombies. ?? just means the process isn't attached to a terminal. that's perfectly normal. in all UNIX systems, including osx, a zombie process is marked with a Z. its parent process will always be 1 (init). try a ps -aux & see if there are any zombies from that output.
10.5: Mail, sent messages, and zombie process problems
You are correct; I used the wrong term. They're not really zombies (as they do vanish when you quit Mail, and my understanding of a zombie is that it wouldn't do that), but they are apparently dead processes that are spawned then not killed off each time you send a message.

Oh, they most certainly are zombies on my system:
10.5: Mail, sent messages, and zombie process problems
note i didn't say these processes weren't zombies, only that the way they were shown in the hint didn't indicate it one way or the other. since i don't use mail.app, i've not had this issue. that mail.app spawns a huge number of children & then fails to reap their status is extremely poor programming practice. given osx threads, i'm amazed they've resorted to something as cack-handed as this. if users are complaining about these children clogging their process table to the point of failed app launches, a bug probably needs to be filed at bugreport.apple.com. |
