Defunct processes

How do I avoid getting defunct processes when starting weblogic 4.5 on Unix.Thanx

"kill -9 pid" should do it.
If it doesn't work then you will get rid of them after rebooting...

Getting Defunct processes while using Oracle iPlanet Web Server 7.0.9 in Solaris 10

Hi,
I have installed Oracle iPlanet Web Server 7.0.9 in our Solaris 10. \
Successfully Configured iPlanet web server using the manual and the application scripts are working fine with this iPlanet webserver.
Even if the application is working fine, the iPlanet webserver stop responding at a period of time and needs to be restart manually...
Found that lots of defunct processes(PPID of webservd) are created and these defuncts (zombies) leads to stop the services.
I am not good in iPlanet webserver configuration settings on the Solaris 10 OS.
Could anyone help me to fix this issue ?
Thanks,
Antony.

FNDLIBR defunct process on RAC/PCP

Hi,
EBS - 12.1.3
DB - 11.2.0.1
OS - Redhat Linux
In one of our client we have RAC with PCP setup.
We are facing issue of FNDLIBR defunct process on one of our application node.

This defunct process get cleared by itself after some time.
Could you please advise, what causing this process to go into defunct state and get cleared by itself.

A defunct process, just like a regular process, may be able to keep a file open on the filesystem. If you stop the environment to take a backup, and processes are still left running when the backup starts, the backup is not clean. Doesn't matter if the process is defunct or not. It's the system telling you there is a problem with a process. The bigger picture is that they often go away by themselves, but after what time ? Is it 1 second, 1 minute, 1 hour ... ? The longer, the worse the problem. Some may not go away. In most cases, the explication is that it is a known feature when you stop component X, and you can determine an average time frame in which these processes continue to live, before they are gone.
FNDLIBR and defunct are know to be a common combination spotted, but they should disappear after some minutes, assuming no requests are still running.

any ideas? Thank

- which OS & version are you running into this issue ?
- By definition, defunct processes (or zombie processes) are processes that have exited prior to it's parent calling a wait() on it to get the return status .
- couple of things I can think of to narrow down the cause of this issue
1. disable ASP & php plugins and see if this still causes this issue
2. try starting the web server with log level to finest and see fi you get any useful information from the server error logs
hope this helps

Is this a "Warehouse Builder" issue? If so, please post your question under Warehouse Builder forum, probably you would get a better response there.

Now from last 7 days , our production server creates a lot of "defunct process" which consumes a lot or resource (i think) and r production server's PAGING space goes to 76% above .
In this moment , anybody plz tell me ,
why defunct process is created and how can I get rid of this problem ?
Is the problem is related with the application ?
Plz reply me ASAP .. ...

Defunct process

Hi all
I found a lot of defunct process in one of our solaris server. It is occupying around 95% of the memory.I killed all those defunct processes, but memory is not yet released.Anybody have an idea about how to release that memory without rebooting the system
Regards
RPS

Yup. I believe the "small amount of system memory" that it mentions is in fact the allocation for the exit status.
You will almost certainly run out of PIDs before you notice the memory consumed by the zombies.
Heck, I've got a box here I can abuse, let's try it. It's even painfully low on memory, being an Ultra-10 with 192MB and Solaris 10 and I'm logged in with a JDS desktop. "max_nprocs" on this machine is 2922.
I ran this command:
# perl -e 'while (1) { $a = fork(); if (!defined $a) {print "Unable to fork. $! Sleeping.\n" ; sleep 30; exit; } elsif ($a == 0) { $b = 7 ; $b++; exit; } }'
(The math with $b is just there so that the child does something besides exit, hopefully forcing at least one page allocation that should be returned).
When it finished, 'prstat' went from 75 processes to 2919 (pretty close to 2922).
vmstat went crazy during the run (and load was over 50 temporarily), but it settled down.
0 0 0 413928 34360 0 52 0 0 0 0 0 0 0 0 0 406 979 402 6 4 90

0 0 0 413472 35760 0 52 0 0 0 0 0 0 0 0 0 402 984 266 4 3 92
[parent exits and all the zombies are reaped]
0 0 0 413800 36736 0 53 0 0 0 0 0 0 0 0 0 402 3267 250 6 16 78
0 0 0 413888 36984 0 52 0 0 0 0 0 1 0 0 0 406 901 258 4 3 93
So, yes. A bit of memory was returned. For over 2800 zombies, something on the order of 400 kb was returned on exit. That's about 140 bytes per process.
'vmstat' isn't necessarily completely accurate and something else on the machine may have affected the output. Assume that the above could be off by 100% or more and it's still not a signifcant amount..

Solution for defunct processes

Hi All,
          I am having a problem on how to avoid getting defunct processes when running
          weblogic server 5.1 on Unix.
          All Ideas are welcomed.
          Thanks in advance.
          Regards,
          Swarup


I am not sure which version of Unix are you on? Make sure you have all the
          recommended patches from sun.

Monitor defunct process

Monitoring defunct process doesn't seem to work
adding a row in the process monitoring module with
name pattern "<defunct>"
doesn't matches any thing (Process count = 0)
where in fact, there is at least 10 on the host
how is this module suppose to work?
thanks

Hi Phler2,

how is this module suppose to work?I'm don't think the stock Process Monitoring module will pick up a defunct/zombie state. If you're just looking for raw zombie count it's in the SystemMonitor module:

How to clear Acroread defunct process in Linux?

Acrobat Reader plugin works fine for first document, but if I close the pdf window and wait ~20 seconds, the Acroread process goes defunct and further attempts to read pdf docs do not display (blank screen). Have tried disabling all other plugins and many extensions. Killing nspluginwrapper manually allows proper pdf reading (for one more doc). This has been going on for a number of Firefox releases.
ps info:
11976 ? Sl 0:00 \_ /usr/lib/firefox-7.0.1/plugin-container /usr/lib/nspluginwrapper/plugins/npwrapper.nppdf.so -greomni /usr/lib/firefox-7.0.1/omni.jar 11767 true plugin
11989 ? S 0:01 \_ /usr/lib/nspluginwrapper/i386/linux/npviewer.bin --plugin /opt/Adobe/Reader9/Browser/intellinux/nppdf.so --connection /org/wrapper/NSPlugins/nppdf.so/11976-2
12000 ? Z 0:01 \_ [acroread] <defunct>
The question: Is there something that can be done to fix the problem in Firefox or is it purely an Adobe problem?

I remember this has been a problem since Ubuntu 9.10 (maybe). It seems that Firefox 3.0+ has a non-robust interface with Adobe PDF reader. Chrome doesn't have this problem on Linux. So I guess the problem is in the plug-inn wrapper. I think Firefox team need to fix this problem ASAP.

Defunct Process in Linux

I´m using a Java Stored Procedure to execute a shell in Linux.
Prcedure that calls the java source
PROCEDURE p_wcsmsg (cmd1 IN VARCHAR2)
AS LANGUAGE JAVA
NAME 'Wcsmsg.execute (java.lang.String)';
Java Source
create or replace and compile java source named wcsmsg as
import java.lang.*;
import java.io.*;
public class Wcsmsg
+{+
public static void execute (String cmd1) throws IOException
+{+
String[] CommandWcsmsg = {"/bin/bash", "-c", cmd1};
Runtime.getRuntime().exec(CommandWcsmsg);
+}+
+}+
Shell:
JAVA_ROOT=/usr/lib/SunJava2-1.4.2/jre
+JCMD="${JAVA_ROOT}/bin/java"+
+$JCMD -cp /bin/wcsmsg/ Wcsmsg+
When that shell is executed, is created a zombie process:
++oracle 16179 0.4 0.0 0 0 ? Z 17:07 0:00 [bash] <defunct>++
That process can´t killed because is a zombie process.
How can I prevent this process becomes a zombie prcess?

When it is modified for this script is displayed the following error
Code
create or replace and compile java source named wcsmsg as
import java.lang.*;
import java.io.*;
public class Wcsmsg

process.waitFor();

Blank PDFs in Linux with [acroread] defunct Adobe Reader 9.4

I am having an issue on a SuSE 11 sp1 box where opening a pdf after closing one gives me a blank screen.
a ps -ef | grep acro* shows [acroread]<defunct> for the acroread process that was running.
I noticed that I can open & close as many as 20 pdfs from a web page with no problem. Everytime I close one out I leave an additional acroread defunct process running. I can do this all day long.
If I close out one & go to a different web page to open a pdf, I get the blank screen and the ps -ef | grep acro* never shows a process starting.
This is becoming a critical issue here. The answer to just restart the browser every time is not gonna fly around here.

Adobe Readler 9.4.2-1

Any thoughts here?
Thanks,

This is not a mozilla bug, as far as I can see. It rather appears to be Adobe's fault.
Anyway, I had the same problem and, since I could not find a solution in the web, I wrote a small workaround program.

You'll find some hint on what's under the hood in the comment at the beginning of the file acroread_interceptor.c
Hope it will help you.

The reason for still seeing that process via the process listing table in the kernel, is a parent process issue.
When the child process terminates, the kernel sends a signal to the parent process to inform the parent of that. A defunct child process means that the parent process has not (yet) acknowledge that signal. And until it does, the child process entry will remain in the process table.
