Can you help me understand what you think the bug is?

Relay is assigned a consensus weight that is too high w/r/t rate
limit.  Excess weight appears to be due to high quality of TCP/IP
connectivity and low latency of relay.  Result is overloaded relay and
poor end-use latency.

Is Tor using more bandwidth that the BandwidthRate?

No, but relay is loaded to flat-line maximum and clearly is attracting
too many circuits.

If so, this is a bug, and should be reported on the Tor Trac.

Not interested in doing that.  Looking for a way to get it work.

If the relay stays overloaded I'll try a packet-dropping IPTABLES rule
to "dirty-up" the connection.

Please reduce your BandwidthRate until your relay load is what you want it to be, or wait until the bandwidth authorities notice your relay is overloaded and reduce its consensus weight.

Dropping packets using IPTABLES will actually increase your relayâs load due to retransmits, and degrade the performance of clients which use your relay. An IPTABLES rule would also degrade the performance of the overall Tor network due to these same retransmits.
