[rabbitmq-discuss] Rabbitmq up and running but connection_closed_abruptly

Fri Sep 6 14:23:25 BST 2013

Simon, thank you very much for your help!

Yes I figured that if my connection was closed those connections would not
listed

I actually killed the connections yesterday and they kept coming back under
different pids

I started the zenoss service that connects to rabbitmq and it looks like
its trying to connect to a PID that does not exist which it sounds like
from your e-mail that that is ok?

sorry I am running a little slow this morning but I couldn't get that
command to work all together but was able to just run it with pid option

rabbitmqctl list_connections zenoss localhost client_properties pid
Listing connections ...
Error: {bad_argument,zenoss}

tail /var/log/rabbitmq/rabbit\@localhost.log

...done.

Is there anyway to turn on more logging?
