zombie process refuses to die

zombie process refuses to die

[Gregory Nowak]

Hi all.

Whenever I take the system down to init level 1 (single user mode), and bring it back up to init level 3 (multiuser mode)
under slackware, the khttpd manager process goes zombie, and refuses to die.

I've tried killall "khttpd manager", and kill pid, but nothing works.

Is there anything else I can do short of rebooting?

Thanks in advance.

Greg

yes, if you're not using khttpd, recompile your kernel without support for it.
That'll not only get rid of it, but it'll make your kernel smaller, and less ram hungry at the same time.

Ok. But, if you're running apache, doesn't khttpd help with the load or some such?

My understanding of it was that khttpd is an in-kernel http server,
that is, it sort of replaces apache rather than speeding it up.
If you want to speed apache up though you should look at squid's web accelerator support, which you will find much more stable and mature.
even the kernel folks can't decide which of httpd, Tux, or nothing at all is a better kernel based http server, so i don't think the whole project is meant to be taken very seriously at this point.
Squid on the other hand does work well as a http accelerator, as well as being a very fine piece of web cache software.

Did you try a "killall -9 khttpd?"  Sending signal 9 is supposed to work
in nearly every case.  It kills a process ungracefully, so it is supposed
to be a last resort.  For example, sending it to an editor would kill the
editor without giving it a chance to save any recovery information and any
changes to a file would be lost.

Yeah, I've tried it, but no luck.

Given what Aaron said, I'll pull it out of the kernel.

I remember some kind of process like that in the 2.4.18 kernel that had to
do with my SCSI card that my scanner is attached to.  It didn't respond to
a signal 9 or anything.  In 2.4.19 and later, it exits like it's supposed
to.  Sounds like a kernel bug to me.  I agree, take it out of the kernel.

the label of the auth disk also tells the tale.
