[rabbitmq-discuss] server crashes with very fast consumers

John,

Thanks for looking into this problem!

Actually these failures would affect the tests.  The goal of the tests is 
consuming 50 GB of messages from 1000 queues simultaneously.  If run.sh could 
not start 1000 producers, there won't be 50 GB messages backed up in the 
broker.  amqp_producer.c can be modified to publish those messages into 1000 
topics with single process, however, we still need to start 1000 consumers to 
consume messages simultaneously.   I am using RHEL5 and did not run into any 
kernel limitations with 1000 producers and 1000 consumers.  Have you tried 
"ulimit" to workaround it?
