Try killing the process ID group with:

Code:
/bin/kill -$(/usr/bin/tail -1 ${pidFile})


Note: you are passing a negative number of the parent shell to kill. all child shells should be in the process group of the parent shell.

Also, some implementations of kill require -- to avoid -$PID being interpreted as a signal number eg:
Code:
/bin/kill -- $(/usr/bin/tail -1 ${pidFile})
