Hi. I'm the sysadmin of an unnamed computer club, we support online security and privacy, so our website is available via a Tor hidden service. Recently, we found a surge of CPU and RAM usage as soon as Tor has been started. A closer look showed it was the result of a DoS script, likely a broken web crawler, or a bot written by some script kiddies, which has been trapped inside an infinite loop and made more than 20 requests per seconds 24 hours a day.
I have defeated the abuser by blacklisting the abused script, which takes a lot of system resource to generate a webpage but never used by normal visitors. The system is pretty good now, but I noticed that the Tor process still consumes significant higher memory usage than before because of the persistent abuser. Is there a way to limit resource usage originated from a single Tor circuit?
