That's to be expected if the connection is not actually talking AMQP. 
You can suppress these warnings, see 'log_levels' at

So I assume the problem is that you don't think these connections should 
be listed, since you think they were short-lived not-really-AMQP 
connections from a monitoring tool?

Connections which have been closed (abruptly or not) should really not 
make it to this list. You might want to attempt to correlate the 
connection pid (e.g. "<0.470.0>" from the log above) with the results of 
"rabbitmqctl list_connections user peer_host peer_port pid state". If 
you see the same pid in both, that's a bug.

But actually I think those are real client connections that have somehow 
been routed to your host B, since the ones from zenoss should never have 
got as far as the 'running' state.

"rabbitmqctl list_connections user peer_host peer_port 
client_properties" might be illuminating - this will add a column 
listing the self-declared client properties to the output, only real 
AMQP clients will have such properties.

Cheers, Simon
