script zumbi (defunct)

["Thiago Silveira Alexandre" <thsalex@gmail.com>]

Galera, to om um problema nesse script q esta mais embaixo. Ele executa ate o ultimo comando mas não termina a execução, quando eu dou um ps pra ver os processos aparece lá que ele virou um processo zumbi (defunct). jah revisei o script varias vezes e nao achei o que tah causando isso. Se alguem já teve essa experiencia por favor me ajude.
abrigado
