escalations

[Pete Dewell]

Could it be user permissions on the restart? I had a similar problem 
where the script was apparently not being restarted. In the end I had to 
use sudo to get the event handler to work properly.
Which user is actually running the event handler? Try suing to that user 
and then running the restart script - see whether the user is allowed to 
do the job.
