[rabbitmq-discuss] BrokerUnreachableException on .NET client

[Steve Eichert]

As Aaron mentioned I've run the same code on OSX via mono and have
encountered similar errors.  I've been getting somewhat inconsistent results
depending on how many threads I spin up.  When set to run 500 threads I'm
currently getting the error below [1].  I do get a number of messages sent
to the queue (~24k) and based on the error am assuming the client can't
handle spinning up that many concurrent connections.

None of the specified endpoints were reachable
Endpoints attempted:
  endpoint=amqp-0-8://localhost:5672, attempts=1, outcome=Too many open
files

Matthias,

Steve ran the exact same code on mono under OSX.  He also encountered some
> errors on the client side.  He will be joining this thread soon.

 Thanks,

 Aaron
