I've been trying out the RabbitMQ river, but have quickly hit problems.

Here's what I am doing::

1. I sent 2,500 messages to RabbitMQ, each containing 100 documents in  
bulk api format
2. I create a RabbitMQ river using curl, with bulk size 1 (I tried 100  
first BTW, and got the same result)
3. About 40,000 documents get indexed OK by elasticsearch

elasticsearch them crashes with:

Exception in thread "elasticsearch[Nameless One][rabbitmq\_river][T#1]"

> java.lang.OutOfMemoryError: unable to create new native thread  
> at java.lang.Thread.start0(Native Method)  
> at java.lang.Thread.start(Thread.java:691)

> org.elasticsearch.river.rabbitmq.RabbitmqRiver$Consumer.run(RabbitmqRiver.java:291)

I'm running elasticsearch 0.19.10, with version 1.4.0 of the RabbitMQ  
river. The river I created is accessing a remote instance of RabbitMQ.

I've read in this group that others are using this river successfully, so  
was not expecting this - am I doing something wrong?
