Hey,
new non-exit relay, Debian 11, tor 0.4.7.8-1~d11.bullseye+1, ~ 1 week old (-> no guard)
KVM VM with atm 4 cores, host passthrough AMD EPYC (-> AES HW accel.).
As can be seen at the attached screenshots memory consumption is irritating as well as the quite high CPU load.
All was fine when it had ~100 Mbit/s but then onion skins exploded (110 per second -> up to 4k per second) as well as CPU and memory.
Tor complains:
Your computer is too slow to handle this many circuit creation
requests! Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy.
And from time to time memory killer takes action
torrc is pretty basic:
Nickname 123 ContactInfo 123 RunAsDaemon 1 Log notice syslog RelayBandwidthRate 2X MBytes RelayBandwidthBurst 2X MBytes SocksPort 0 ControlSocket 0 CookieAuthentication 0 AvoidDiskWrites 1 Address xxxx OutboundBindAddress yyyy ORPort xxxx:yyy Address [zzzz] OutboundBindAddress [zzz] ORPort [zzz]:xxx MetricsPort hhhh:sss MetricsPortPolicy accept fffffff DirPort yy Sandbox 1 NoExec 1 CellStatistics 1 ExtraInfoStatistics 1 ConnDirectionStatistics 1 EntryStatistics 1 ExitPortStatistics 1 HiddenServiceStatistics 1
Ideas/suggestions (apart from limiting BW) to fix this?
Thanks
fran
