Operating Systems Linux Red Hat How to get rid of zombie process?

It appears to be gone. Frankly, unless you want to do this as a hobby, there are much more important things to worry about than the occasional zombie.

And as mentioned above, consider getting the developer/vendor to fix the zombie problem. What you are doing is closing the barn door after the livestock has already been stolen.

Hi,
I did not see the Zombie process until now, but one thing i have noticed here is :
it was the Java Process(for WebLogic server) that was running in to Zombie
when i look for the Java Path and java version, it cant find, below is the output.
what do you guys suggest ?
Code:
[cmsprod@drcmsapp303 ~]$ which java
/usr/bin/which: no java in (.:/u01/app/oracle/product/11.2/db_1/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/cmsprod/bin:/u01/app/oracle/product/10.2/agent10g/bin)
[cmsprod@drcmsapp303 ~]$ java -version
-bash: java: command not found
[cmsprod@drcmsapp303 ~]$

Thanks

Well, you do not have JAVA PATH'd, but they do! Smilie

JAVA can be installed anywhere. I'd expect JAVA to have a thread taking sigchld calls.

Walk the tree back to 1 to see how the zombie got launched.

You might strace the parent to see if they are in a loop, but like the man said, coding error. If it is a java parent, maybe it needs to do a Process.waitfor(): Process (Java Platform SE 6)() Not sure, good question for JAVA gurus up at Oracle.
