[tor-talk] Error binding network socket: Address already in use

[Moritz Bartl]

Hi,

I see a lot of scary warnings in the Tor logs on our high bandwidth
nodes (>400 Mbps): "Error binding network socket: Address already in use".

All servers are configured equally, running multiple Tor processes. I
also apply sysctl tweaks, see
http://www.torservers.net/misc/config/sysctl.conf

I would appreciate if someone could help diagnose the problem. Find me
on IRC (nickname gamambel/gamamb) or Jabber (same as email address).

DirPorts are bound to local ports and Lighttpd is used as a reverse
proxy to tunnel requests on all IPs to one DirPort.

Example torrc:
