[App_rpt-users] hub crash help

[Steve Zingman]

Peter,
I prefer finding the problem rather then scripting work arounds. That 
being said, You may want to consider moving up to Debian 8 which 
supports systemd. The systemd unit will restart ASL quickly in case of a 
crash.
Again, this is not the way to solve the issue, but it may help until we 
can find and fix the problem.
