Full Discussion: SIGTERM failing in AIX
Operating Systems AIX SIGTERM failing in AIX Post 302998862 by Don Cragun on Thursday 8th of June 2017 06:45:59 PM

I presume that:
  1. the script that you showed us that you're trying to kill is not the actual code that you're trying to kill,
  2. that you are not the author of the code you're trying to kill (since you didn't know the trap was there), and
  3. that you didn't consult with the author of that script before trying to write code to kill it
.
One obvious reason why someone would add a trap command to ignore signals to a script that is expected to run for a while (i.e., more than a 1 instruction cycle) would be to keep scripts like yours from randomly killing them. Trying to ignore SIGSTOP and SIGKILL produces undefined results, but it is certainly a reasonable first attempt to keep a script running while the author of that script tracks down why their script is being terminated for no obvious reason.

kill.d

kill.d(1m)							   USER COMMANDS							kill.d(1m)

NAME

       kill.d - snoop process signals as they occur. Uses DTrace.

SYNOPSIS

       kill.d

DESCRIPTION

       kill.d is a simple DTrace program to print details of process signals as they are sent, such as the PID source and destination, signal num-
       ber and result.

       This program can be used to determine which process is sending signals to which other process.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       Default output, print process signals as they are sent.
	      # kill.d

FIELDS

       FROM   source PID

       COMMAND
	      source command name

       TO     destination PID

       SIG    destination signal ("9" for a kill -9)

       RESULT result of signal (-1 is for failure)

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       kill.d will run forever until Ctrl-C is hit.
