[nzlug] can not kill a process

[anru chen]

stoped sendmail use sendmail init script , the process is still here,
looks like only way to get rid of it is to reboot machine.

since rex said this process is still in running state and can be
interrupted, then
how to do that? or which log file i should look for?
