Unable to kill java process

GSK_2 — Tue, 04 Apr 2006 01:47:20 GMT

I was unable to kill the java process (pid 12960). It was consuming 100% CPU and it does not have any child processes either. Can anyone of you suggest what can be done. I have pasted the top details below for information. Thanks in advance.

Hi Satish,

PPID of 12960 (Java process) has some how became 1. You need to reboot the machine in order to kill the process.

Hi,
Do a reboot.

or try this way,

1. Login to the machine as apidsma1
2. Execute kill -9 -1.

This will kill all running process of the apidsma1 user.

HTH,

Hi,

Please note that when you stop the java process you should be in the proper path, this will ensure that a clean stop of java process, as they require some LIB path.

to kill this process just try a kill -15 , this should get killed.

Hi Guys,

Thanks for your suggestion. We finally had to reboot after trying all the above suggestions.

Hi,
probably the process is waiting for i/o. In this case it becomes unkillable (has non-signalable priority). Be aware that this behavior could means badly coded (written) application. Use tusc for syscall trace to see what the given process is doing or what waiting for.
