[tor-relays] [warn] Request too large from address '[scrubbed]' to DirPort. Closing.

Hi, last night the log of one of my nodes showed within 2 minutes about 160 of these messages. Traffic stats show that the incoming bandwidth increased from the average of 300 Mbit/s to more than 400 Mbit/s, where at the same time outgoing traffic dropped. From the peak I see, the requests must have been really big. Does anyone noticed this on other tor servers too? Regards, Klaus
