You can adjust the log level for connection-related events. See the 
log_levels variable in 
http://www.rabbitmq.com/configure.html#configuration-file. This may not 
be fine-grained enough for you though since to suppress the errors from 
the above LB connections you'd have to set the connection log_level to 
'none', thus suppressing logging of all connection-related events.
