[rabbitmq-discuss] while would a close/fin of a connection elicit a reset/rst by rabbitmq?

Fri May 3 21:15:52 BST 2013

Some of my rabbitmq servers don't do graceful closes, no idea why.
This is a localhost unit test, it is just opening a connection, then
closing it, and now the outgoing close is eliciting a reset.

The log doesn't say much, is there any way to increase its verbosity?

With rabbitmq 3.0.4, on debian, installed from the rmq apt repo.
