Hi I run a small Guard relay that was fine until yesterday. It got attacked and lost the Guard and the Stable flag. At first I thought I could get away with my small RPi 4 relay. Seems to be a very widespread attack against Guards. Best, Mike On 13.10.2026 17:31, 3hn92a--- via tor-relays wrote:
Hi there. My very first relay is 33 days old and I got under attack 3 times, but it go HSDir flag 5 times - dont know what is the pattern. Two times when it worked stable was after lowering the Bandwidth to 20 MByte.
I don't give up. I set MaxMeminQueues to 1/3 of total memory and (in o proper .conf file ) MemoryHigh twice as MaxMemInQueues and MemoryMax to aprrox 2/3 of total memory hoping there is a way of getting rid of OOM Killer. If this isn't enough next time I will think of ram to double ( more expensive VPS ) while leaving MaxMemInQueues and MemoryHigh at same level. Maybe there will enough space to delay OOM Killer long enough to wait attack is over? Am I thinking correctly or is it stupid?

Nope, looks like that patch did nothing whatsoever. The relay I tested it on is still receiving over 10,000 BEGIN_DIRs every second.
I don't understand why. But limiting the number of BEGIN_DIR requests per circuit per second should be very easy for someone familiar with the code. I will try a few more attempts myself.
