[rabbitmq-discuss] RabbitMQ timing out under small load

Well, when I say connectivity problems I mean the following things:

1) On either of the nodes, running the command rabbitmqctl list_queues as
root would time out about 80% of the time. It seemed that there would be
brief periods where the command would work, and then that would be
subsequently followed by another longer period where it no longer was
2) Running a local script to perform gets from the queue would frequently
exception out with a timeout error, and retry 30 seconds later, and
continually time out. Beyond that, if I remember correctly, running a script
like this to drain the queue seemed to work better on one node than the
other (namely, it didn't time out the connection) but even though it was
making progress, it was only able to pull one item from the queue every 2-3

For our application we opted to not use subscriptions for the consumers,
they pretty much just sit in a loop and call get, sleeping when there is no
work to be done.

Overall I'm pretty skeptical that this was a network related issue, simply
because as soon as the two large queues were deleted and re-created
everything instantly started working again. But then again I'm no erlang
expert :)

Thanks again for the help!
