Hello,

Thanks for running a relay.

You are on 0.2.9.11 and #20059 was merged in 0.2.9.12
https://gitweb.torproject.org/tor.git/tree/ReleaseNotes?h=release-0.2.9

There is no sense to report this further because the issue is fixed, you
are just one release behind.

As for the relay, I am pretty sure there is a firewall or something
which throttles the incoming / outgoing TCP connection a
process/user/pid can initiate or something like this. The problem is
either in the operating system itself either a network-level firewall or
built-in router firewall.
