[rabbitmq-discuss] Limitations with RabbitMQ Java Client

[k.madnani84]

Hi,

I am using the RabbitMQ Java client 3.1.5 to test the performance using
MultiCastMain.java.But my RabbitMQ crashes when executing the following
scenario:
Total Time Limit: 60s
Sampling Interval: 20s
No. Of Producer(s): 1000
No. Of Consumer(s): 1000
Minimum Size of a Message: 3000 byte
Messages Auto Acknowledged while Consumption: YES
Queue Properties: '1000 Queues each assigned to one consumer; Auto
Generated; Durable; Exclusive;'
Exchange Type: 'direct'
Message Properties: Message is Persistent;

My Memory High Watermark is 4.7 GB.

Is there any benchmark on how many consumers and producers maximum i can use
with the above watermark.

i am facing this error at client end:
