 Hello.
 I installed the torus on my server (debian 8), included in torrc
 HiddenService.
 .onion domains are working. But I ran into the problem, the DDOS attack on
 HiddenService, at this point the TOR process consumes 100% of the
 processor core and the domains stop working.
 NumCPUs does not work, the TOP process still consumes 100% of the kernel.
 Tor version 0.3.3.3-alpha (tried different)
 What options for solving the problem can you advise?
