[tor-relays] Botnet issues and upgrading to 0.2.4.x

[Chris Whittleston]

Ok - I have 0.2.4.17-rc built and running on the Pi - I'll give it 24-48
hours to see if the same problem with sudden increases in the number of
circuits happens again, then try the MaxAdvertisedBandwidth setting in case
it helps.

Will drop feedback here in a couple of days - thanks for the help all!

Chris
