[rabbitmq-discuss] queue memory issues

[Guillem Corominas]

Hi all,

I am using RabbitMQ to send data messages between 2 java applications in 
2 different machines.
Sometimes the RabbitMQ broker crashes because the queues are too large, 
due to large comunication cuts (days).
I tried using MessageProperties.PERSISTENT_BASIC when performing 
basicPublish action, so it persists the messages to disk, but the 
problem doesn't
solve by doing that.

I would really apreciate if someone could help me solve a couple of 
questions (or tell me where to look at, I've looked up in the API and 
docs, but couldn't find it):
a) how can I give more memory to the rabbit to store (both memory and 
persistent) messages?
b) is it possible to make the queue discard old messages when queue 
reaches it limit, so at least the RabbitMQ broker doesn't crash?

thanks in advance,
