Last night for 4h30 (until VPS provider shut it down) one of my middle relays seems to have got in a bad state where it was using 100% CPU continuously
It was not using much bandwidth, about 4MB/s, but reading the logs it seems it was getting a lot of circuit requests (70K/minute initially, 100K at the end). Is there anything I can do about it?
