kill_task.sh script does not work for child processes

Current Situation

• A shell job executed for Agents with Unix includes a "sleep" command.
• When the job is killed from the JOC Cockpit (kill task immediately operation) then the Agent task is killed, the child task running the "sleep" command is not killed.
• The problem seems to be related to the kill_task.sh script that does not traverse child pids when executing the line

  for _child in `$psTree | egrep " $1\$" | awk '{ print $1 }'`; do
  

  as this loop does not return any child pids.

Desired Behavior

• All descendants of tasks should be reliably killed by the kill_task.sh script.

Patch

• A patch for JobScheduler Agent 1.12.7 is here available.
  • Stop JobScheduler Agent
  • Copy the downloaded jar file to ./lib/patches
  • Start JobScheduler Agent
