Lots of connections

[Ben Wilhelm <zorba@xxxxxxxxxxxxx>]

I've been playing with stressing Tor out recently. I've encountered some 
rather weird and suboptimal behavior. If you hit it with a lot of 
connections simultaneously it starts spitting out "Giving up on 
unattached conn (60 sec old)." errors (and those numbers go up 
dramatically if you *really* stress it badly :P) From browsing the 
source, it looks like that's its way of saying "I don't have enough open 
Tor routes, and I'm having trouble getting more fast enough, so I'm 
going to start dropping connections". And, yes, it does appear to be 
dropping connections.

Which is obviously not really ideal.

Is this diagnosis accurate? If so, is it on the list of Things That 
Should Be Fixed, or is this low priority/unimportant? And if this 
diagnosis isn't accurate, what's going on? :)

(One thought, from going over in my mind what it looks like - they also 
come in clumps often, and that's when the numbers start getting big. 
Maybe something is blocking for long periods of time that you're not 
expecting, and that's just making it time out when it should be handling 
the load no problem? Its CPU usage doesn't seem to be high.)

Thanks,
