PD: you function compiled fine :)

>> Hi everyone!
>> I'm trying to configure a new cpu+auth server using the instructions in the

>> 3, followed the wiki instructions to set up a cpu+auth server (compiled my

>> 3, run /n/9fat/venti -s -c /dev/sdC0/arenas -a 'tcp!127.1!17034' -h
>> 'tcp!127.1!8000'
>> it suicides here too
