Try this.

Do a ps -aef|grep (your PID#)

# ps -aef |grep 13647

# ps -aef |grep (parent PID#) To find the process that possibly spawned your process "gzip -c".

If it has a parent PID. a process that spawned this process, then you should try to kill that process.

Keep trying to find the parent in this manner until you find the true parent. Then you should be able to kill this PID as well.
