Re: zombies - half solved
How are zombies best dealt with, correctively? Sorry to answer my own question. The solution was to find the parent process and kill it. But the second question still stands, is there a generic way to prevent the formation of zombies? The cause in this specific case is a perl-based CGI script called by apache2. Regards, -Lars

The easiest way might be to let perl auto-reap the children for you.
It's as simple as prepending this line within the block that spawns the
child processes:
local $SIG{CHLD} = 'IGNORE'; # straight outa perlipc(1)
One thing to watch out for though is that you may get weird side effects
if you set this and then use system() in the same scope. If so, just
use wait/waitpid instead (it's only a few more lines of code).
