Still under heavy attack even with the MaxMemInQueues and 0.3.2.8-rc. I need 2 xeons to push 30 mbit as a guard/middle …

Do you want to share some information:

Type i) (memory exhaustion by too many circuits) What is the memory(top) per tor and its MaxMemInQueues ? How many circuits per hour in log ?

Type ii) (cpu exhaustion by too many 'half open' tor connections) Is your number of open files normal (fw in place) and moderate connection counts per remote IP ?

Type iii) (One fills your server with too many long fat pipes, first ACK and RTT) If on Freebsd, is "mbuf clusters in use" (netstat -m) moderate ? Do you get "kern.ipc.nmbclusters limit reached" in messages ?
