FWIW: On many UNIX and Linux systems zombies will not go away with a kill signal (or even kill -9) and the only way to clear them off the process table is to reboot.
I've seen them clear themselves, that is they disappear from "top". Does that mean that the parent has started up again and started the zombie child up?
I've seen this on our works FreeBSD webserver.

TAPSET::KPROCESS(3stap) 												   TAPSET::KPROCESS(3stap)

NAME
tapset::kprocess - systemtap kernel process probe points DESCRIPTION
This family of probe points is used to probe the kernel's process activities. It contains the following probe points: kprocess.create Fires whenever a new process is successfully created, either as a result of one of the fork syscall variants, or a new kernel thread. Arguments: task a handle to the newly created process new_pid pid of the newly created process kprocess.start Fires immediately before a new process begins execution. Arguments: N/A kprocess.exec Fires whenever a process attempts to exec to a new program Arguments: filename the path to the new executable kprocess.exec_complete Fires at the completion of an exec call Arguments: errno the error number resulting from the exec success a boolean indicating whether the exec was successful kprocess.exit Fires when a process terminates. This will always be followed by a kprocess.release, though the latter may be delayed if the process waits in a zombie state. Arguments: code the exit code of the process kprocess.release Fires when a process is released from the kernel. This always follows a kprocess.exit, though it may be delayed somewhat if the process waits in a zombie state. Arguments: task a task handle to the process being released pid pid of the process being released SEE ALSO
