Hi,

I am fairly new to Tor and have been running a relay for a couple of weeks.

I have configured a RelayBandwithRate of only 100 KB and so only see a few active connections at any one time.

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.)

Is this part of the rolling connection set of this host or something else?

Eg:

#netstat -e

Active Internet connections (w/o servers)

Proto Recv-Q Send-Q Local Address           Foreign Address         State       User       Inode   

...
