Is there any way to kill a zombie process without reboot?Here is how it happens:
I wanted to download a 12GB torrent.After adding the .torrent file, transmission turned into a zombie process.I tried ktorrent too.Same behavior.Finally I could download the file using µTorrent but after closing the program, it turns into a zombie as well.
I tried using kill skill and pkill with different options and -9 signal but no success.
In some answers in web I found out killing the parent can kill the zombie, but killing wine didn't help either.
Is there another way?
