How to identify the Defunc processes in system, to improve the performance, memory utilisation, load average

[Pete Randall]

Usually they're clearly lableled as such. Do a "ps -ef |grep defunct" and you'll see them if you have any.

Hi,

Most of the defunct process will be running with the same name "defunct". There are also few process with PPID 1. Try doing a trace for these process, and if you find they are not doing anything, they can also be considered defunct. Also check out the top output. Check if there are any process running on top that have gone into a loop. Clearing these process would improve the performance.

you have to below commands
# ps -elf
if status('s) field is shown'Z' S(status)
that is zombie process.
also
# ps -ef
you will see 'defunct' syntax

I use a simple script:
ps -ef | grep defunct | grep -v grep

This will give you any defunct processes.

Hi

The defunct process can be seen when u do a ps -ef command
#ps -ef |grep -i defunct

You can see if there are any.
