Killing "?" process

[Victor Wang]

Hi,
I did a "ps -ef|grep java" and noticed there are several java processes. I tried killing these processes but failed to do so.

May I know what processes are these that are having "?". How do I kill such processes?

This is a HP11 with dual processors.

Could anyone help me with this problem?

hp20> ps -ef|grep java
root 18302 18264 0 Feb 6 ? 0:00 /usr/bin/hp700_ux_11.00/pkgs/java/1.4.0.

root 17612 1 0 Feb 6 ? 0:00 /usr/bin/hp700_ux_11.00/pkgs/java/1.4.0.

etooi 29870 1 0 Feb 9 ? 0:00 /usr/bin/hp700_ux_11.00/pkgs/java/1.4.0.

root 21070 1 0 Feb 6 ? 0:00 /usr/bin/hp700_ux_11.00/pkgs/java/1.4.0.

Thanks

Hi

The ? field you are querying is valid. If the process has a controlling terminal such as a ksh (shell) process then you will see ttyp (terminal id) etc. In this case the java process does not have a controlling terminal (started in the background, or a daemon etc)

To kill the processes use the pid (process id's in the 2nd column. The parent of these processes (3rd column) is init. You don't want to kill him

ie

kill 18302

Hi,

why do you want to kill these jobs in the first place and what happens if you use:
kill -9 18302
?

Hi,

Are you having trouble killing these processes?. As mentioned already, these processes are not associated with any terminal which means they were started in the background. You can try the following to duplicate this behaviour

$nohup sleep 30&
$exit

Login again

$ps -ef |grep sleep

You should see the sleep process with "?" in it's tty column

$kill

Should kill it

The script I'm attaching is capbable of killing question mark processes.

It won't look for root processes for obvious reasons. See attachment.

Hi, this looks like a problem on which we are working on.
You should take a TOC of your system, and open a call to HP support.

To get more information on where these processes come from, check out the parentprocesses not being 1. In this case, the first line has a parent with process ID 18264. You can check what that is with 'ps -fp 18264

This can give you some insight on where they come from, and so help you prevent them from getting started in the first place if you really don't need them, though some configuration tools on HP-UX are already in Java, like the veritas volume manager, so they could be perfectly legal. And it could also be those java processes are started by your website...
