Are you referring to defunct process or just some child process whose parent has exited ? Hence grepping for "Z" as in "zombie" ?
will give you the last 10 processes that took most CPU time, if this helps.
When I run the top command, it shows 1 process as being Stopped. This is not a zombie, but simply a stopped process. Unfortunately, I can't figure out how to tell which process this is, nor why it is in a stopped state? Any way of finding this out? (7 Replies)
I can write a script to use ps and interigate the output, but is there a command that works similar to the find command for files where I can request a list of all the running processes over 1 day old ?
thanks! (8 Replies)
Hi,
top process is shows like this in solaris server oracle 8i running:
load averages: 5.01, 3.35, 2.82 18:24:45
344 processes: 332 sleeping, 5 running, 2 stopped, 5 on cpu
CPU states: 22.2% idle, 29.6% user, 14.7% kernel, 33.5% iowait, 0.0% swap... (3 Replies)
I let a script A call script B.
I used
nohup a.sh &>/tmp/log &
In script A it calls B directly, without any redirecting or nohup or background.
However A is always "Stopped", while B is running correctly. Anybody knows why?
thanks!

Hi. Before throwing my question, thanks to everybody for paying attention. Sorry if my english isn't good enough, but it's not my mother tongue.
That's my question:

Does that not work on a stopped process? I've tried to kill a stopped process and it is not working. Or do you need a certain type of shell for this to work? I don't see anything about this in my man pages. (3 Replies)
Hi:
I have a program written in FORTRAN running on AIX platform.
It is because missing of documentation and without root password, therefore we want to modify the program so that we can find out which script/program that call this FORTRAN program.

preap(1) User Commands preap(1)NAME
preap - force a defunct process to be reaped by its parent
SYNOPSIS
preap [-F] pid...
DESCRIPTION
A defunct (or zombie) process is one whose exit status has yet to be reaped by its parent. The exit status is reaped via the wait(3C),
waitid(2), or waitpid(3C) system call. In the normal course of system operation, zombies may occur, but are typically short-lived. This may
happen if a parent exits without having reaped the exit status of some or all of its children. In that case, those children are reparented
to PID 1. See init(1M), which periodically reaps such processes.
An irresponsible parent process may not exit for a very long time and thus leave zombies on the system. Since the operating system destroys
nearly all components of a process before it becomes defunct, such defunct processes do not normally impact system operation. However, they
do consume a small amount of system memory.
preap forces the parent of the process specified by pid to waitid(3C) for pid, if pid represents a defunct process.
preap will attempt to prevent the administrator from unwisely reaping a child process which might soon be reaped by the parent, if:
o The process is a child of init(1M).
o The parent process is stopped and might wait on the child when it is again allowed to run.
o The process has been defunct for less than one minute.
OPTIONS
The following option is supported:
-F Forces the parent to reap the child, overriding safety checks.
OPERANDS
The following operand is supported:
pid Process ID list.
EXIT STATUS
The following exit values are returned by preap, which prints the exit status of each target process reaped:
0 Successfully operation.
non-zero Failure, such as no such process, permission denied, or invalid option.

SEE ALSO proc(1), init(1M), waitid(2), wait(3C), waitpid(3C), proc(4), attributes(5)WARNINGS
preap should be applied sparingly and only in situations in which the administrator or developer has confirmed that defunct processes will
not be reaped by the parent process. Otherwise, applying preap may damage the parent process in unpredictable ways.
