Re: [tor-dev] Idle connections in netstat

Recently I have been noticing, in netstat output, a high level of established but idle TCP connections to other tor-hosts.

(Out of 96 ESTABLISHED connections there are 90 with Recv-Q & Send-Q of 0.)

That pretty normal. Recv-Q get drained as fast as the tor process can read it (I don't see any nonzero on my relay), and Send-Q only takes the time of the TCP ACK from the other side to go back to zero, so with casual surfing over the circuits you don't see many nonzero Q values - only a dozen of the hundreds of connections on my relay.
