SYNOPSIS:    Can't kill a process

OS RELEASE:  Solaris 2.x

PRODUCT:

KEYWORDS:   signal kill process


DESCRIPTION: 

No matter which signal is specified in a kill command a process won't
die. 


SOLUTION:

A process is "hung" not responding to any signals from the kill command.
The reason for this behavior is the process is generally sleeping on an I/O
operation. A missed interrupt is a prime cause.  An example is a runaway
tape read operation.  When a process is sleeping on an I/O operation all
signals are ignored.  This is an age-old problem in the UNIX world.
