[tor-relays] Tor automatic restart

[s7r]

Hi,

I don't see the problem in being How to automatically restart Tor. The 
base problem is, why do you need to restart it regularly or at every x 
period?

I mean, I only restart my Tor when I apply updates to Tor or to the 
operating system, etc. -- otherwise it works fine. If something hangs 
your Tor process and you need to restart it, you have to determine the 
cause of that.

What OS and which version, hardware and setup (bare metal, virtual 
machine) do you use?
What are the system resources (CPU,RAM,HDD/SSD,Bandwidth)?
How did you install Tor? Package manager or other method?
What is your soft and hard max open files limit?
