[tor-relays] Re: Shutting down my ~40 guards

[Jack via tor-relays <tor-relays@xxxxxxxxxxxxxxxxxxxx>]

I have been experiencing the same attack against my relays. Highly 
asymmetrical traffic flood until the tor process runs out of memory and 
is restarted.

The attack stops when the HSDir flag is lost. I've doubled the amount of 
memory available as a temporary work around. For now none of my relays 
have reacquired the HSDir flag and are not being attacked, including guards.
