I can kill the script and 'hammer mirror-stream' processes with

pkill -f /usr/bin/lockf -k -t 0 .lockfile ./hms

and

pkill -f hammer mirror-stream /Backup1/Data /Backup2/Data

But I am not able to kill the kernel helper threads

They don't get killed when the 'hammer mirror-stream processes is killed.
How do I kill them?

Thanks
