Yes I know that's the main problem :)

It's 1.3e-3 from debian lenny.

I'm not allowed to raise the ulimit above 1024. This certain message
also just appears once every 6 hours so I don't think it's that
important but the libevent errors come really often.

Yes I read this already and there is also the ConstrainedSockets
mentioned. But in the Tor-Manpage is written this should be used if I
get the:"Error creating network socket: No buffer space available"
message in the logs but my error is different. Or has this message been
replaced with the one I get? If this option is usefull what is a good
value? Is there any way except try and error to know which socketsize
shall be used with me?
