Description (partial)

Node resets during a massive revertion of SSON circuits

High number of circuits concurrently reverting on a node. 
On the side port where the SSON circuit are restored are present many (main or restored) other circuits.

Saying that S is the number of SSON circuits and T the total number of circuit on the restoration side (so T >= S);
the problem can arise if: 
   S * T * 2 > 6000

The worst case is if all the circuits are SSON ones (S = T):
 - 54 is a safe number
 - having more than 54 circuits can highlight the problem
