Anyone know of a sure way to kill a process?

I recently had a process that would not die.

I tried all the typical kill commands, with no succes.
Finally, ugh, a reboot ended this processs with 9 lives.

Any suggestions would be appreciated.

your best shot is kill -9 <pid>
However, if these are zombie processes,you cant kill them, that usually
means the parent processes does something wrong. Not to worry, they use
very little resources(no memory, open files et.c.). If however the process
is stuck in a D state you cant kill it, usually means the kernel have done
something wrong.
Look at the output of "top" or ps -aux, the STAT column will say
Z (zombie) or D

I was told, a long time ago, that such a process is waiting on a
hardware interupt, and would die (if killed) when it received that
interupt.

I guess there may be other reasons though. Especially as the above
was regarding unix on a Unisys box about 9 years ago :-)

Well, that was the problem....the stuck process was eating 80 percent
of my memory.

did you try

kill -9 <pid>

if that dont work, is the process defunct? (man ps). if so try killing
the parent process (man pstree)

Another worth trying is kill -15 <pid>.

I've met several processes which refused to die with SIGKILL, but went
smoothly six-feet-under with SIGTERM. Dunno why...

Did you add -9 to the kill command?
