Generate a core for a hung process

[John Tyler]

Hi!

I am trying to generate a core dump of a hung process. i tried kill -11 with no luck. THere is no existing core file which can prevent a new core file from being created. The parent process is the init process.

Is there any other way to force the process to dump core.

Any thoughts or ideas?

thanks.

Hi John,

If the parent is init, the process is a zombie and will not respond to signals. You can't kill them no matter what you try. The only way to get rid of them is to reboot.

Instead of trying to get it to dump, why not leave it hung and examine the memory?

Or if you can do a TOC and then examine the crash files.

Also does the process have sufficient permission to write where it is being started from?

Hi,

Maybe you can do something with truss/tusc truss is the Solaris version, beleave tusc is the HPux version.
